Functions

func CeilToPowerOfTwo

func CeilToPowerOfTwo(n int) int

CeilToPowerOfTwo returns n if it is a power-of-two, otherwise the next-highest power-of-two.

func ClosestPowerOfTwo

func ClosestPowerOfTwo(n int) int

ClosestPowerOfTwo returns n if it is a power-of-two, otherwise the closest power-of-two.

func FloorToPowerOfTwo

func FloorToPowerOfTwo(n int) int

FloorToPowerOfTwo returns n if it is a power-of-two, otherwise the next-highest power-of-two.

func IsPowerOfTwo

func IsPowerOfTwo(n int) bool

IsPowerOfTwo reports whether the given n is a power of two.
