Function IsPowerOfTwoLeftShift

math/binary/checkisnumberpoweroftwo.go:30–37

IsPowerOfTwoLeftShift This function takes advantage of the fact that left shifting a number by 1 is equivalent to multiplying by 2. For example, binary 00000001 when shifted by 3 becomes 00001000, which in decimal system is 8 or = 2 * 2 * 2

(number uint)

// by 1 is equivalent to multiplying by 2. For example, binary 00000001 when shifted by 3 becomes 00001000,
// which in decimal system is 8 or = 2 * 2 * 2
func IsPowerOfTwoLeftShift(number uint) bool {
	for p := uint(1); p <= number; p = p << 1 {
		if number == p {
			return true
		}
	}
	return false
