From Clark Nelson:
In my opinion, exactly how and where the macro is defined that indicates our
conformance to the FP standard
doesn't really matter. The point is that it is our intention to conform, at
least to some degree and under
some circumstances.
R. David Murray added the comment:
Note that Chris' patch is coming from Intel. (The ICC buildbots are currently

have to worry about differentiating between the python
Chris Hogan added the comment:
Producing NaN by Py_HUGE_VAL / Py_HUGE_VAL as in the suggested patch is unsafe
as it can generate a FP exception during runtime. Also aggresive compiler FP
optimizations can eliminate this calculation on compile-time. For this reason,
we've used constant
Mark Dickinson added the comment:
Looks fine to me. IIRC, we moved the PyFloat_FromString implementation away
from using Py_NAN in Python 3 for exactly this reason.

An aggressively optimizing compiler could treat 0 * x = 0 no matter what x is.

Note that defaulting to unsafe math in extensions will make *their* use of the

If we go that route (-fp-model strict for Python build, but not for
extensions), we should also apply the attached patch that defines Py_NAN as

Using -fp-model strict (or other appropriate icc flag) seems like a reasonable

It should likely also be applied to Python 3.x, despite the version field of

New submission from Hrvoje Nikšić:
On a Python compiled with Intel C compiler, float('nan') returns 0.0. This
behavior can be reproduced with icc versions 11 and 12.
The definition of Py_NAN in include/pymath.h expects `HUGE_VAL * 0.0` to
compile to a NaN value on IEEE754 platforms

What's `sys.float_repr_style` for this build? For Python 3.5 and short float
repr, `float('nan')` shouldn't even be using Py_NAN. It should land in
_Py_parse_inf_or_nan in pystrtod.c, which uses `_Py_dg_stdnan` to get the NaN
value directly from a suitable
Hrvoje Nikšić added the comment:
sys.float_repr_style is 'short'.
I haven't actually tried this in Python 3.5, but I did note the same definition
of Py_NAN (which is used elsewhere in the code), so I tagged the issue as
likely also present in 3.x.

So I believe that this particular issue (float('nan') giving zero) should not

There are two aspects to this. (1) Currently, at least in theory, CPython

Stefan Krah added the comment:
I agree we should add -fp-model strict to the icc build flags, provided that
there is a way that it does not show up in the distutils flags.
Apparently icc users want unsafe fast math by default, so this flag should
probably not be enforced in extension module
