Sure.

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
