0/0 is exactly as undefined for integers as 0.0/0.0 is for floating
point. To see why that is true, please try to identify a finite floating
point value for f that is NOT a solution to this equation:

0.0*f eq 0.0

Then try to find an integer value for i that is NOT a solution for

0*i eq 0

Is it any easier for the integer case than for the floating point case?
