I see that you have commented that y=0 is an error, I assume that you
are using that internally.  If you do mod any number with 0, that is a
math error because it is a divide by zero exception.  Why it came up as
floating point exception would depend on how the compiler arbitrated the
evaluation of the if clause I think.
