[New-bugs-announce] [issue3501] expm1 missing

[Mike Speciner]

New submission from Mike Speciner <speciner_michael at emc.com>:

The math module contains log1p but is missing expm1 (the inverse of
log1p). These functions are necessary to avoid loss of precision in
floating point calculations, and are part of the C99 standard math library.
