I would multiply everything by 10 or 100, calculate the mod(A,B), then
divide by 10 or 100.
mod(A,B) stand for the remainder of an integer division. It don't play
well with a non-integer divisor. At least, that's what I tend to assume.
You can use something like :
#declare Something = mod(N*10, 1)/10;
This is functionally identical to what you want.
