  Not neccessarily wrong, but you could also check the first bit. If it’s 1 the number is uneven, if it’s 0 the number is even. That seems to be more efficient.

    Huh… That makes sense. Til. Ran some tests but speed is pretty similar. Only 4% faster using bitmath or 300 milliseconds difference after 10mil runs.

    Modern compilers and interpreters are smart enough to figure out what you’re trying to do and automatically do that for you.
