Re: [Numpy-discussion] numpy.float64(numpy.NaN)!=numpy.NaN

[Sasha <nd...@ma...>]

BTW,

>>> from numpy import *
>>> nan =3D=3D nan
False

>>> from decimal import *
>>> Decimal('NaN') =3D=3D Decimal('NaN')
False

and finally (may not work on all platforms):

>>> float('NaN') =3D=3D float('NaN')
False
