Not to take from all the funny answers ... but

bool IsEven(int i) => (i & 1) != 1;

(C#)

Though, obviously I had to come up with some ridiculous solutions:

bool IsEven(int i) => ((Func<string, bool>)(s => s[^1] == 48))($"{i:B}");

This one works without conditionals :)

bool IsEven(int i)
{
    try
    {
        int _ = (i & 1) / (i & 1);
    }
    catch (Exception)
    {
        return true;
    }

    return false;
}

s[^1]

Ohh wow, I've been learning it casually for years, and I didn't know that existed in C#. I guess I should go back and hit the books some more.
