New submission from Mark Dickinson <[email protected]>:
Two problems with float.fromhex:
(1) it incorrectly rejects trailing whitespace on infs and nans:
>>> float.fromhex('a.0 ')
10.0
>>> float.fromhex('nan ')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid hexadecimal floating-point string
(2) The implementation uses PyOS_strnicmp for detecting nans and infs,
which is locale-aware. A locale-unaware case-insensitive comparison
should be used instead. I don't know of any locale where this actually
makes a difference, but I think it should be fixed anyway.
