You have not understood the concept of floating point data and of their binary representation. For a starter, please try to write the *exact* value 1.0/3.0 with a finite number of decimal digits. A basic paper on this was available here: http://cch.loria.fr/documentation/IEEE754/ACM/goldberg.pdf Any attempt to solve your problem by giving a different number of trailing zeros is bound to fail. You best drop the approach of using equality predicates for floating point data, it will not work in the general case.
