Well, C has INFINITY from math.h; but on script languages it may not be
available, so you have to resort on
1.0/0.0; this generates a "Division by Zero exception", and if it's not
trapped, the result is INFINITY.

So I think that either the fp exception is being trapped, or the code is
using integer arithmetic.
