You're not addressing my point, though, so I was probably not clear
enough. My surprize was not that a % b was equal to b in this case, and
so not strictly smaller than b (because I expect such things when
working with floats). My surprize was that Decimals don't even try to
be between 0 and b, and sometimes give a result that is far outside the
range. This surprized me because I expected floats and Decimals to try
to give "approximately equal" results...
A bientot,
Armin
