func BitCount(v uint32) uint32

Bitcount returns the number of set bits in v

func Cbrt(n uint32) uint32

Cbrt returns the integer cube root of n. That is to say, the r such that:

r * r * r <= n && n < (r + 1) * (r + 1) * (r + 1)

Adapted from code found in Hacker's Delight, fixed by Fabian Giessen https://gist.github.com/729557

func GCD(a, b uint32) uint32

GCD returns the greatest common divisor of a and b.

func Log10(n uint32) uint32

Log10 returns log base 10 of n. n == 0 returns 0

func Log2(n uint32) (r uint32)

Log2 returns log base 2 of n. It's the same as index of the highest bit set in n. n == 0 returns 0

func Max(x, y uint32) uint32

Max(x,y) returns the larger of x or y

func Min(x, y uint32) uint32

Min(x,y) returns the smaller of x or y

func Pow(x, y uint32) (r uint32)

Pow returns x**y, the base-x exponential of y.

func Sqrt(x uint32) uint32

Sqrt returns the square root of x. Based on code found in Hacker's Delight (Addison-Wesley, 2003): http://www.hackersdelight.org/

func TrailingZeros(v uint32) uint32

TrailingZeros returns the number of trailing 0 bits in v. If v is 0, it returns 0.
