    So what? It works and it’s better than precompiling a list of all known even and odd numbers, and expecting a computer to iterate through a whole list every time it wants to check the value of something.

    The stupid trig tables are just as problematic and it’s why graphics chips use other geometric functions instead. It’s just better to use a modulus.
