Thanks Alok, that's more or less what I'm doing. I have my weights array with rounded numbers but when I put them back to the envelope, they get converted into floating point approximations.
In Maya, the rounded weights get stored in the ma file, I'm not sure how Maya deal with that internally though, I'm guessing it's similar.
