See [link math_toolkit.error_handling error handling documentation]
|
||
|
|
for a detailed explanation of the mechanism of handling errors,
|
||
|
|
including the common "bad" arguments to distributions and functions,
|
||
|
|
and how to use __policy_section to control it.
|
||
|
|
|
||
|
|
But, by default, *exceptions will be raised*, for domain errors,
|
||
|
|
pole errors, numeric overflow, and internal evaluation errors.
|
||
|
|
To avoid the exceptions from getting thrown and instead get
|
||
|
|
an appropriate value returned, usually a NaN (domain errors
|
||
|
|
pole errors or internal errors), or infinity (from overflow),
|
||
|
|
you need to change the policy.

[caution If throwing of exceptions is enabled (the default) but
|
||
|
|
you do *not* have try & catch block,
|
||
|
|
then the program will terminate with an uncaught exception and probably abort.
|
||
|
|
|
||
|
|
Therefore to get the benefit of helpful error messages, enabling *all exceptions
|
||
|
|
and using try & catch* is recommended for most applications.
|
||
|
|
|
||
|
|
However, for simplicity, the is not done for most examples.]
