|  | 
 | ||
|  | [h4 Math-2.5.1 (Boost-1.63)] | ||
|  | 
 | ||
|  | Patches: | ||
|  | 
 | ||
|  | * Fixed evaluation of zero polynomial in polynomial.hpp, see [@https://svn.boost.org/trac/boost/ticket/12532 12532]. | ||
|  | * Fixed missing header include in boost/math/tools/tuple.hpp, see [@https://svn.boost.org/trac/boost/ticket/12537 12537]. | ||
|  | 
 | ||
|  | [h4 Math-2.5.0 (Boost-1.62)] | ||
|  | 
 | ||
|  | New Features: | ||
|  | 
 | ||
|  | * Enabled all the special function code to work correctly with types whose precision can change at runtime: for example type `mpfr_float` from Boost.Multiprecision. | ||
|  | 
 | ||
|  | Patches: | ||
|  | 
 | ||
|  | * Fix tgamma_delta_ratio for cases where the delta is small compared to the base. | ||
|  | * Fix misc GCC-4.4 test failures. | ||
|  | 
 | ||
|  | [h4 Math-2.4.0 (Boost-1.61)] | ||
|  | 
 | ||
|  | New Features: | ||
|  | 
 | ||
|  | * Polynomial arithmetic added to tools. | ||
|  | 
 | ||
|  | 
 | ||
|  | [h4 Math-2.3.0 (Boost-1.60)] | ||
|  | 
 | ||
|  | New Features: | ||
|  | 
 | ||
|  | * Promote the root finding and function minimization code to first class citizens - these are now officially supported as part of the library. | ||
|  | * Allow the library to be used and tested with compiler exception handling support turned off.  To better facilitate this | ||
|  | the default error handling policies have been changed to ['errno_on_error] but only when the compiler has no exception handling support. | ||
|  | 
 | ||
|  | Patches: | ||
|  | 
 | ||
|  | * Fix behaviour of the non-central chi-squared distribution when the non-centrality parameter is zero to match the chi-squared, | ||
|  | see [@https://svn.boost.org/trac/boost/ticket/11557 11557]. | ||
|  | * Fix comments in code for the hypergeometric to match what it actually does, also fixes the parameter access functions to return | ||
|  | the correct values.  See [@https://svn.boost.org/trac/boost/ticket/11556 11556]. | ||
|  | * Stopped using hidden visiblity library build with the Oracle compiler as it leads to unresolved externals from the C++ standard library. | ||
|  | See [@https://svn.boost.org/trac/boost/ticket/11547 11547]. | ||
|  | * Fix unintended use of __declspec when building with Oracle C++.  See [@https://svn.boost.org/trac/boost/ticket/11546 11546]. | ||
|  | * Fix corner case bug in root bracketing code, see [@https://svn.boost.org/trac/boost/ticket/11532 11532]. | ||
|  | * Add some missing typecasts in arguments to std::max in Bernoulli code.  See [@https://svn.boost.org/trac/boost/ticket/11453 11453]. | ||
|  | * Fix mistaken assumptions about the possible values for FLT_EVAL_METHOD.  See [@https://svn.boost.org/trac/boost/ticket/11429 11429]. | ||
|  | * Completely revamped performance testing and error-rate measuring code so we can more easily document how well (or not!) we're doing. | ||
|  | This information will hopefully get more frequently updated in future as it's more or less automatically generated - see the /reporting/ | ||
|  | sub-directory for more information. | ||
|  | * Fix some corner cases in the beta, incomplete beta, and incomplete beta derivative.  With thanks to Rocco Romeo. | ||
|  | * Reorganized the Bessel functions internally to improve the performance of Jn and Yn. | ||
|  | * Fixed skewness formula for triangular distribution, see [@https://svn.boost.org/trac/boost/ticket/11768 #11768]. | ||
|  | * Fixed some examples so they compile on Unix platforms which have an ::exception struct declared, see [@https://svn.boost.org/trac/boost/ticket/11827 #11827]. | ||
|  | * Correct mistake in triangular distribution skewness formula [@https://svn.boost.org/trac/boost/ticket/11768 11768], | ||
|  | reported by Juan Leni. | ||
|  | 
 | ||
|  | [h4 Math-2.2.1] | ||
|  | 
 | ||
|  | Patch release for Boost-1.58: | ||
|  | 
 | ||
|  | * Minor [@https://github.com/boostorg/math/pull/13#issuecomment-98905579 patch for Haiku support.] | ||
|  | * Fix the decimal digit count for 128-bit floating point types. | ||
|  | * Fix a few documentation typos. | ||
|  | 
 | ||
|  | [h4 Math-2.2.0 (boost-1.58.0)] | ||
|  | 
 | ||
|  | * Added two new special functions - __trigamma and __polygamma. | ||
|  | * Fixed namespace scope constants so they are constexpr on conforming compilers, see https://svn.boost.org/trac/boost/ticket/10901. | ||
|  | * Fixed various cases of spurious under/overflow in the incomplete beta and gamma functions, plus the elliptic integrals, | ||
|  | with thanks to Rocco Romeo. | ||
|  | * Fix 3-arg __legendre_p and __legendre_q functions to not call the policy based overload if the final argument | ||
|  | is not actually a policy. | ||
|  | * Cleaned up some dead code in the incomplete beta function, see [@https://svn.boost.org/trac/boost/ticket/10985 #10985]. | ||
|  | * Fixed extreme-value pdf for large valued inputs, see [@https://svn.boost.org/trac/boost/ticket/10938 #10938]. | ||
|  | * Large update to the Elliptic integral code to use Carlson's latest algorithms - these should be more stable, more accurate | ||
|  | and slightly faster than before.  Also added support for Carlson's RG integral. | ||
|  | * Added __ellint_d, __jacobi_zeta and __heuman_lambda elliptic integrals. | ||
|  | * Switched documentation to use SVG rather than PNG graphs and equations - browsers seem to have finally caught up! | ||
|  | 
 | ||
|  | [h4 Math-2.1.0 (boost-1.57.0)] | ||
|  | 
 | ||
|  | * Added __hyperexponential_distrib. | ||
|  | * Fix some spurious overflows in the incomplete gamma functions (with thanks to Rocco Romeo). | ||
|  | * Fix bug in derivative of incomplete beta when a = b = 0.5 - this also effects several non-central distributions, | ||
|  | see [@https://svn.boost.org/trac/boost/ticket/10480 10480]. | ||
|  | * Fixed some corner cases in __round. | ||
|  | * Don't support 80-bit floats in cstdfloat.hpp if standard library support is broken. | ||
|  | 
 | ||
|  | [h4 Math-2.0.0 (Boost-1.56.0)] | ||
|  | 
 | ||
|  | * [*Breaking change]: moved a number of non-core headers that are predominantly used for internal | ||
|  | maintenance into `libs/math/include_private`.  The headers effected are `boost/math/tools/test_data.hpp`, | ||
|  | `boost/math/tools/remez.hpp`, `boost/math/constants/generate.hpp`, `boost/math/tools/solve.hpp`, | ||
|  | `boost/math/tools/test.hpp`. | ||
|  | You can continue to use these headers by adding `libs/math/include_private` to your compiler's include path. | ||
|  | * [*Breaking change]: A number of distributions and special functions were returning the maximum finite value | ||
|  | rather than raising an __overflow_error, this has now been fixed, which means these functions now behave as | ||
|  | documented.  However, since the default behavior on raising an __overflow_error is to throw a `std::overflow_error` | ||
|  | exception, applications which have come to reply rely on these functions not throwing may experience exceptions | ||
|  | where they did not before.  The special functions involved are __gamma_p_inva, __gamma_q_inva, | ||
|  | __ibeta_inva, __ibetac_inva, __ibeta_invb, __ibetac_invb, __gamma_p_inv, __gamma_q_inv.  The distributions | ||
|  | involved are __pareto_distrib, __beta_distrib, __geometric_distrib, __negative_binomial_distrib, | ||
|  | __binomial_distrib, __chi_squared_distrib, __gamma_distrib, __inverse_chi_squared_distrib, | ||
|  | __inverse_gamma_distrib.  See [@https://svn.boost.org/trac/boost/ticket/10111 #10111]. | ||
|  | * Fix __round and __trunc functions so they can be used with integer arguments, see [@https://svn.boost.org/trac/boost/ticket/10066 #10066]. | ||
|  | * Fix Halley iteration to handle zero derivative (with non-zero second derivative), see [@https://svn.boost.org/trac/boost/ticket/10046 #10046]. | ||
|  | 
 | ||
|  | [h4 Math-1.9.1] | ||
|  | 
 | ||
|  | * Fix Geometric distribution use of Policies, see [@https://svn.boost.org/trac/boost/ticket/9833 #9833]. | ||
|  | * Fix corner cases in the negative binomial distribution, see [@https://svn.boost.org/trac/boost/ticket/9834 #9834]. | ||
|  | * Fix compilation failures on Mac OS. | ||
|  | 
 | ||
|  | [h4 Math-1.9.0] | ||
|  | 
 | ||
|  | * Changed version number to new Boost.Math specific version now that we're in the modular Boost world. | ||
|  | * Added __bernoulli_numbers, changed arbitrary precision __tgamma/__lgamma to use Sterling's approximation (from Nikhar Agrawal). | ||
|  | * Added first derivatives of the Bessel functions: __cyl_bessel_j_prime, __cyl_neumann_prime, __cyl_bessel_i_prime, __cyl_bessel_k_prime, __sph_bessel_prime and __sph_neumann_prime (from Anton Bikineev). | ||
|  | * Fixed buggy Student's t example code, along with docs for testing sample means for equivalence. | ||
|  | * Documented `max_iter` parameter in root finding code better, see [@https://svn.boost.org/trac/boost/ticket/9225 #9225]. | ||
|  | * Add option to explicitly enable/disable use of __float128 in constants code, see [@https://svn.boost.org/trac/boost/ticket/9240 #9240]. | ||
|  | * Cleaned up handling of negative values in Bessel I0 and I1 code (removed dead code), see [@https://svn.boost.org/trac/boost/ticket/9512 #9512]. | ||
|  | * Fixed handling of very small values passed to __tgamma and __lgamma so they don't generate spurious overflows (thanks to Rocco Romeo). | ||
|  | * [@https://svn.boost.org/trac/boost/ticket/9672 #9672 PDF and CDF of a Laplace distribution throwing domain_error] | ||
|  | Random variate can now be infinite. | ||
|  | * Fixed several corner cases in __rising_factorial, __falling_factorial and __tgamma_delta_ratio with thanks to Rocco Romeo. | ||
|  | * Fixed several corner cases in __rising_factorial, __falling_factorial and __tgamma_delta_ratio (thanks to Rocco Romeo). | ||
|  | * Removed constant `pow23_four_minus_pi ` whose value did not match the name (and was unused by Boost.Math), see | ||
|  | [@https://svn.boost.org/trac/boost/ticket/9712 #9712]. | ||
|  | 
 | ||
|  | [h4 Boost-1.55] | ||
|  | 
 | ||
|  | * Suppress numerous warnings (mostly from GCC-4.8 and MSVC) [@https://svn.boost.org/trac/boost/ticket/8384 #8384], [@https://svn.boost.org/trac/boost/ticket/8855 #8855], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/9107 #9107], [@https://svn.boost.org/trac/boost/ticket/9109 #9109].. | ||
|  | * Fixed PGI compilation issue [@https://svn.boost.org/trac/boost/ticket/8333 #8333]. | ||
|  | * Fixed PGI constant value initialization issue that caused erf to generate incorrect results [@https://svn.boost.org/trac/boost/ticket/8621 #8621]. | ||
|  | * Prevent macro expansion of some C99 macros that are also C++ functions [@https://svn.boost.org/trac/boost/ticket/8732 #8732] and [@https://svn.boost.org/trac/boost/ticket/8733 #8733].. | ||
|  | * Fixed Student's T distribution to behave correctly with huge degrees of freedom (larger than the largest representable integer) [@https://svn.boost.org/trac/boost/ticket/8837 #8837]. | ||
|  | * Make some core functions usable with `long double` even when the platform has no standard library `long double` support [@https://svn.boost.org/trac/boost/ticket/8940 #8940]. | ||
|  | * Fix error handling of distributions to catch invalid scale and location parameters when the random variable is infinite [@https://svn.boost.org/trac/boost/ticket/9042 #9042] and [@https://svn.boost.org/trac/boost/ticket/9126 #9126]. | ||
|  | * Add workaround for broken <tuple> in Intel C++ 14 [@https://svn.boost.org/trac/boost/ticket/9087 #9087]. | ||
|  | * Improve consistency of argument reduction in the elliptic integrals [@https://svn.boost.org/trac/boost/ticket/9104 #9104]. | ||
|  | * Fix bug in inverse incomplete beta that results in cancellation errors when the beta function is really an arcsine or Student's T distribution. | ||
|  | * Fix issue in Bessel I and K function continued fractions that causes spurious over/underflow. | ||
|  | * Add improvement to non-central chi squared distribution quantile due to Thomas Luu, | ||
|  | [@http://discovery.ucl.ac.uk/1482128/ Fast and accurate parallel computation of quantile functions for random number generation, Doctorial Thesis 2016]. | ||
|  | [@http://discovery.ucl.ac.uk/1463470/ Efficient and Accurate Parallel Inversion of the Gamma Distribution, Thomas Luu] | ||
|  | [h4 Boost-1.54] | ||
|  | 
 | ||
|  | * Major reorganization to incorporate other Boost.Math like Integer Utilities Integer Utilities (Greatest Common Divisor and Least Common Multiple), quaternions and octonions. | ||
|  | Making new chapter headings. | ||
|  | * Added many references to Boost.Multiprecision and `cpp_dec_float_50` as an example of a User-defined Type (UDT). | ||
|  | * Added Clang to list of supported compilers. | ||
|  | * Fixed constants to use a thread-safe cache of computed values when used at arbitrary precision. | ||
|  | * Added finding zeros of Bessel functions `cyl_bessel_j_zero`, `cyl_neumann_zero`, `airy_ai_zero` and `airy_bi_zero`(by Christopher Kormanyos). | ||
|  | * More accuracy improvements to the Bessel J and Y functions from Rocco Romeo. | ||
|  | * Fixed nasty cyclic dependency bug that caused some headers to not compile [@https://svn.boost.org/trac/boost/ticket/7999 #7999]. | ||
|  | * Fixed bug in __tgamma that caused spurious overflow for arguments between 142.5 and 143. | ||
|  | * Fixed bug in raise_rounding_error that caused it to return an incorrect result when throwing an exception is turned off [@https://svn.boost.org/trac/boost/ticket/7905 #7905]. | ||
|  | * Added minimal __float128 support. | ||
|  | * Fixed bug in edge-cases of poisson quantile [@https://svn.boost.org/trac/boost/ticket/8308 #8308]. | ||
|  | * Adjusted heuristics used in Halley iteration to cope with inverting the incomplete beta in tricky regions | ||
|  | where the derivative is flatlining.  Example is computing the quantile of the Fisher F distribution for probabilities | ||
|  | smaller than machine epsilon.  See ticket [@https://svn.boost.org/trac/boost/ticket/8314 #8314]. | ||
|  | 
 | ||
|  | [h4 Boost-1.53] | ||
|  | 
 | ||
|  | * Fixed issues [@https://svn.boost.org/trac/boost/ticket/7325 #7325], [@https://svn.boost.org/trac/boost/ticket/7415 #7415] | ||
|  | and [@https://svn.boost.org/trac/boost/ticket/7416 #7416], [@https://svn.boost.org/trac/boost/ticket/7183 #7183], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/7649 #7649], [@https://svn.boost.org/trac/boost/ticket/7694 #7694], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/4445 #4445], [@https://svn.boost.org/trac/boost/ticket/7492 #7492], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/7891 #7891], [@https://svn.boost.org/trac/boost/ticket/7429 #7429]. | ||
|  | * Fixed mistake in calculating pooled standard deviation in two-sample students t example | ||
|  | [@https://svn.boost.org/trac/boost/ticket/7402 #7402]. | ||
|  | * Improve complex acos/asin/atan, see [@https://svn.boost.org/trac/boost/ticket/7290 #7290], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/7291 #7291]. | ||
|  | * Improve accuracy in some corner cases of __cyl_bessel_j and __gamma_p/__gamma_q thanks to suggestions from Rocco Romeo. | ||
|  | * Improve accuracy of Bessel J and Y for integer orders thanks to suggestions from Rocco Romeo. | ||
|  | 
 | ||
|  | [h4 Boost-1.52] | ||
|  | 
 | ||
|  | * Corrected moments for small degrees of freedom [@https://svn.boost.org/trac/boost/ticket/7177 #7177] (reported by Thomas Mang). | ||
|  | * Added [link math_toolkit.airy Airy functions] and [link math_toolkit.jacobi Jacobi Elliptic functions]. | ||
|  | * Corrected failure to detect bad parameters in many distributions | ||
|  | [@https://svn.boost.org/trac/boost/ticket/6934 #6934] (reported by Florian Schoppmann) | ||
|  | by adding a function check_out_of_range to test many possible bad parameters. | ||
|  | This test revealed several distributions where the checks for bad parameters were ineffective, | ||
|  | and these have been rectified. | ||
|  | * Fixed issue in Hankel functions that causes incorrect values to be returned for ['x < 0] and [nu] odd, see [@https://svn.boost.org/trac/boost/ticket/7135 #7135]. | ||
|  | * Fixed issues [@https://svn.boost.org/trac/boost/ticket/6517 #6517], [@https://svn.boost.org/trac/boost/ticket/6362 #6362], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/7053 #7053], [@https://svn.boost.org/trac/boost/ticket/2693 #2693], | ||
|  | [@https://svn.boost.org/trac/boost/ticket/6937 #6937], [@https://svn.boost.org/trac/boost/ticket/7099 #7099]. | ||
|  | 
 | ||
|  | 
 | ||
|  | * Permitted infinite degrees of freedom [@https://svn.boost.org/trac/boost/ticket/7259 #7259] | ||
|  | implemented using the normal distribution (requested by Thomas Mang). | ||
|  | * Much enhanced accuracy for large degrees of freedom [nu] and/or large non-centrality [delta] | ||
|  | by switching to use the Students t distribution | ||
|  | (or Normal distribution for infinite degrees of freedom) | ||
|  |  centered at delta, | ||
|  | when [delta] / (4 * [nu])  < epsilon for the floating-point type in use. | ||
|  | [@https://svn.boost.org/trac/boost/ticket/7259 #7259]. | ||
|  | It was found that the incomplete beta was suffering from serious cancellation errors | ||
|  | when degrees of freedom was very large. (That has now been fixed in our code, | ||
|  | but any code based on Didonato and Morris's original papers | ||
|  | (probably every implementation out there actually) will have the same issue). | ||
|  | 
 | ||
|  | [h4 Boost-1.51] | ||
|  | See Boost-1.52 - some items were added but not listed in time for the release. | ||
|  | 
 | ||
|  | [h4 Boost-1.50] | ||
|  | 
 | ||
|  | * Promoted math constants to be 1st class citizens, | ||
|  | including convenient access to the most widely used | ||
|  | built-in float, double, long double via three namespaces. | ||
|  | * Added the Owen's T function and Skew Normal distribution written by Benjamin Sobotta: see __owens_t and skew_normal_distrib. | ||
|  | * Added Hankel functions __cyl_hankel_1, __cyl_hankel_2, __sph_hankel_1 and __sph_hankel_2. | ||
|  | * Corrected issue [@https://svn.boost.org/trac/boost/ticket/6627 #6627 nonfinite_num_put formatting of 0.0 is incorrect] | ||
|  | based on a patch submitted by K R Walker. | ||
|  | * Changed constant initialization mechanism so that it is thread safe even for user-defined types, also | ||
|  | so that user defined types get the full precision of the constant, even when `long double` does not. | ||
|  | So for example 128-bit rational approximations will work with UDT's and do the right thing, even though | ||
|  | `long double` may be only 64 or 80 bits. | ||
|  | * Fixed issue in `bessel_jy` which causes Y[sub 8.5](4[pi]) to yield a NaN. | ||
|  | 
 | ||
|  | [h4 Boost-1.49] | ||
|  | 
 | ||
|  | * Deprecated wrongly named `twothirds` math constant in favour of `two_thirds` (with underscore separator). | ||
|  | (issue [@https://svn.boost.org/trac/boost/ticket/6199 #6199]). | ||
|  | * Refactored test data and some special function code to improve support for arbitary precision and/or expression-template-enabled types. | ||
|  | * Added new faster zeta function evaluation method. | ||
|  | 
 | ||
|  | Fixed issues: | ||
|  | 
 | ||
|  | * Corrected CDF complement for Laplace distribution (issue [@https://svn.boost.org/trac/boost/ticket/6151 #6151]). | ||
|  | * Corrected branch cuts on the complex inverse trig functions, to handle signed zeros (issue [@https://svn.boost.org/trac/boost/ticket/6171 #6171]). | ||
|  | * Fixed bug in `bessel_yn` which caused incorrect overflow errors to be raised for negative ['n] (issue [@https://svn.boost.org/trac/boost/ticket/6367 #6367]). | ||
|  | * Also fixed minor/cosmetic/configuration issues [@https://svn.boost.org/trac/boost/ticket/6120 #6120], [@https://svn.boost.org/trac/boost/ticket/6191 #6191], | ||
|  |   [@https://svn.boost.org/trac/boost/ticket/5982 #5982], [@https://svn.boost.org/trac/boost/ticket/6130 #6130], | ||
|  |   [@https://svn.boost.org/trac/boost/ticket/6234 #6234], [@https://svn.boost.org/trac/boost/ticket/6307 #6307], | ||
|  |   [@https://svn.boost.org/trac/boost/ticket/6192 #6192]. | ||
|  | 
 | ||
|  | [h4 Boost-1.48] | ||
|  | 
 | ||
|  | * Added new series evaluation methods to the cyclic Bessel I, J, K and Y functions. | ||
|  | Also taken great care to avoid spurious over and underflow of these functions. | ||
|  | Fixes issue [@https://svn.boost.org/trac/boost/ticket/5560 #5560] | ||
|  | 
 | ||
|  | * Added an example of using Inverse Chi-Squared distribution for Bayesian statistics, | ||
|  | provided by Thomas Mang. | ||
|  | 
 | ||
|  | * Added tests to use improved version of lexical_cast which handles C99 nonfinites without using globale facets. | ||
|  | 
 | ||
|  | * Corrected wrong out-of-bound uniform distribution CDF complement values [@https://svn.boost.org/trac/boost/ticket/5733 #5733]. | ||
|  | 
 | ||
|  | * Enabled long double support on OpenBSD (issue [@https://svn.boost.org/trac/boost/ticket/6014 #6014]). | ||
|  | 
 | ||
|  | * Changed nextafter and related functions to behave in the same way as other implementations - so that nextafter(+INF, 0) | ||
|  | is a finite value (issue [@https://svn.boost.org/trac/boost/ticket/5823 #5832]). | ||
|  | 
 | ||
|  | * Changed tuple include configuration to fix issue when using in conjunction with Boost.Tr1 (issue [@https://svn.boost.org/trac/boost/ticket/5934 #5934]). | ||
|  | 
 | ||
|  | * Changed class eps_tolerance to behave correctly when both ends of the range are zero (issue [@https://svn.boost.org/trac/boost/ticket/6001 #6001]). | ||
|  | 
 | ||
|  | * Fixed missing include guards on prime.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5927 #5927]). | ||
|  | 
 | ||
|  | * Removed unused/undocumented constants from constants.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5982 #5982]). | ||
|  | 
 | ||
|  | * Fixed missing std:: prefix in nonfinite_num_facets.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5914 #5914]). | ||
|  | 
 | ||
|  | * Minor patches for Cray compiler compatibility. | ||

|  | * Added Policy based framework that allows fine grained control | ||
|  | over function behaviour. | ||
|  | * [*Breaking change:] Changed default behaviour for domain, pole and overflow errors | ||
|  | to throw an exception (based on review feedback), this | ||
|  | behaviour can be customised using __Policy's. | ||
|  | * [*Breaking change:] Changed exception thrown when an internal evaluation error | ||
|  | occurs to boost::math::evaluation_error. | ||
|  | * [*Breaking change:] Changed discrete quantiles to return an integer result: | ||
|  | this is anything up to 20 times faster than finding the true root, this | ||
|  | behaviour can be customised using __Policy's. | ||
|  | * Polynomial/rational function evaluation is now customisable and hopefully | ||
|  | faster than before. | ||
|  | * Added performance test program. | ||

|  | * Implemented root finding algorithms. | ||
|  | * Implemented the inverses of the incomplete gamma and beta functions. | ||
|  | * Rewrite erf/erfc as rational approximations (valid to 128-bit precision). | ||
|  | * Integrated the statistical results generated from | ||
|  | the test data with Boost.Test: uses a database of expected | ||
|  | results, indexed by test, floating point type, platform, and compiler. | ||
|  | * Improved lgamma near 1 and 2 (rational approximations). | ||
|  | * Improved erf/erfc inverses (rational approximations). | ||
