This avoids a possible divide-by-zero in the following calculation, and rounding the number to an integer seems like saner behavior anyway. Assuming IEEE math, the division would yield +Infinity which would get replaced by 1.0 at the bottom of the function, so nothing really interesting would ensue; but avoiding divide-by-zero seems like a good idea on general principles. Per report from Piotr Stefaniak. No back-patch since this seems mostly cosmetic.
