[issue6794] decimal.py: incorrect results in NaN comparisons

[Stefan Krah]

New submission from Stefan Krah stefan-use...@bytereef.org:

Hi,

I believe the following comparisons aren't correct:

1:

Decimal(-sNaN63450748854172416).compare_total(Decimal(-sNaN911993))
== Decimal('1')

Should be: Decimal('-1') (checked against decNumber)


2:
Decimal(NaN1).compare_total_mag(Decimal(-NaN99))
== Decimal('-1')

Should be: Decimal('1') (checked against decNumber)
