func CeilToPowerOfTwo

func CeilToPowerOfTwo(n int) int

CeilToPowerOfTwo returns the least power of two integer value greater than or equal to n.

func FloorToPowerOfTwo

func FloorToPowerOfTwo(n int) int

FloorToPowerOfTwo returns the greatest power of two integer value less than or equal to n.

func IsPowerOfTwo

func IsPowerOfTwo(n int) bool

IsPowerOfTwo reports whether given integer is a power of two.

func StringToBytes

func StringToBytes(s string) (b []byte)
