On MacOSX (10.5) Intel, Python 2.6.4

>>> from decimal import Decimal
>>> min(Decimal('3.0'), 10.2)
10.199999999999999

On Win32, Python 2.6.4

>>> from decimal import Decimal
>>> min(Decimal('3.0'), 10.2)
Decimal('3.0')

On Linux 32 bit, Python 2.6.4

>>> from decimal import Decimal
>>> min(Decimal('3.0'), 10.2)
10.199999999999999

However, the correct result of Win32 version seems completely coincidental, it produces invalid results for other values:

>>> min(Decimal('12.0'), 10.2)
Decimal('12.0')

We are already aware of problems related to float and Decimal comparison, but in this case it complicates matters worse: On Windows code seems to work OK, on other platforms its results are wrong; worse than this, Windows version works totally by coincidence in fact.

It should at least warn user or raise an error IMHO.
