What is the fastest integer division supporting division by zero no matter what the result is?
...
Inspired by some of the comments I got rid of the branch on my Pentium and gcc compiler using

Covariance, Invariance and Contravariance explained in plain English?
...pes, other say it is about type conversion and others say it is used to decide whether a method is overwritten or overloaded.
All of the above.
