I am reading this and still don't understand what is the question. You
should never operate two floating point numbers expecting to result zero.
Period.
WARNING: Advanced material follows.
A 32-bit integer fits losslessly in the mantissa of a Double. Any of
the basic integer operations which work correctly on 32-bit integers
must also work correctly when that integer is stored in a Double. You
are allowed to assume this.
