\brief Basic tests of the nonfinite num facets.
|
|
|
|
\detail If has_infinity and has_nan, then
|
|
basic_test outputs using nonfinite_num_put facet
|
|
and reads back in using nonfinite_num_ facet,
|
|
and checks loopback OK.
|
|
|
|
Also checks that output of infinity, -infinity and NaN are as expected,
|
|
using C99 specification "nan -nan nan -nan" and "inf -inf".
|
|
Also includes a few combinations of display manipulators
|
|
(left, right, internal, showpos)
|
|
and checks that can input C99 infinity and NaN too.
