I disagree with this statement
<quote>But that doesn't change the fact that it will expose the same
rounding-errors as floats do - just for different numbers. </quote>
The example used has no rounding errors. For anything less that 28
significant digits it rounds to 1.0. With floats 1.0/3 yields
0.33333333333333331<-- on my machine. Also you can compare two
decimal.Decimal() objects for equality. With floats you have to test
for a difference less than some small value. BTW, a college professor
who also wrote code for a living made this offhand remark "In general
it is best to multiply first and then divide." Good general advice.
