Here’s a blog article which benchmarks quite a few ways to test if a number is odd or even:

Surprisingly, the fastest way appears to be the modulus % operator, even out performing the bitwise ampersand &, as follows:

if (x % 2 == 0)
total += 1; //even number
total -= 1; //odd number

Definitely worth a read for those that are curious.
