To add to the confusion: >>> str(1.1000000000000001) '1.1' >>> repr(1.1000000000000001) '1.1000000000000001' Floating point numbers are not precise. Decimals are, so they require precise information when they are constructed. If you want to use the rounding that str() uses when you create a Decimal instance, please use that. Decimal(str(x)). By forcing you to do that, Python makes you aware of the problem and you can avoid nasty surprices. If you think that's excessive typing, just define a simple function. def D(x): return Decimal(str(x)) -- http://mail.python.org/mailman/listinfo/python-list
