26.13.2 Limitations and other considerations
Setting up a given processor to trap IEEE-754 floating point errors currently requires custom code on a per-architecture basis. You may have to modify fpectl to control your particular hardware.
Conversion of an IEEE-754 exception to a Python exception requires
that the wrapper macros PyFPE_START_PROTECT
and
PyFPE_END_PROTECT
be inserted into your code in an appropriate
fashion. Python itself has been modified to support the
fpectl module, but many other codes of interest to numerical
analysts have not.
The fpectl module is not thread-safe.
