[New-bugs-announce] [issue12079] decimal.py: TypeError precedence in fma()

[Stefan Krah]

New submission from Stefan Krah <stefan-usenet at bytereef.org>:

Hi, I think that TypeError should take precedence over InvalidOperation
in these two cases:

>>> Decimal('Infinity').fma(Decimal('0'), (3.91224318126786e+19+0j))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.2/decimal.py", line 1879, in fma
    'INF * 0 in fma')
  File "/usr/local/lib/python3.2/decimal.py", line 3926, in _raise_error
    raise error(explanation)
decimal.InvalidOperation: INF * 0 in fma
>>> 


>>> Decimal('1').fma(Decimal('snan'), 1.2222222222)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.2/decimal.py", line 1871, in fma
    return context._raise_error(InvalidOperation, 'sNaN', other)
  File "/usr/local/lib/python3.2/decimal.py", line 3926, in _raise_error
    raise error(explanation)
decimal.InvalidOperation: sNaN
