| Is a small relative to 'norm' ?

This code does the following test 'Abs(a/norm)) < isSmall'.
This code used to be as follows, but it was changed because
using x==y for floats is a bad idea, and eventually caused
trouble on Visual C++. (AJS)
float b = (float) ((double) Abs(a) + norm);
return (b == (float) norm);
