Actually, most of our code uses powers of two.  Still we have to think about 
rounding when, for example, we are converting values from a small of 0.125 to 
a small of 0.5.  But, Adam's suggestion seems to work fine:
    Y := Integer (X / FpB'Small) * FpB'Small;
The resulting x86 assembly code could be improved a little, but I have not 
checked the ARM code yet.
