For small values, Peng is absolutely right. But for large values like 101.17*10 21135 I don't think it matters that much, I think I covered that by rounding 101.17769*10 21135 down to 101.17*10 21135.

Also, may I notice that you usually use the same thing, called division by a constant.(User_blog:LittlePeng9/SCG(1))

This is what happens here in the FSes. Though the constants are here very large.
