Re: for / while else doesn't make sense

ing point is an inexact representation. Just because integers and binary fractions have an exact correspondence we ought not to be affording them special significance. Floating point 1 is not the integer 1, it stands for a range of numbers some fraction either side of 1. There are other ways of handling non-integral numbers, such as fixed point, rational and unum.
