Functions ¶

func And ¶

func And(a, b *big.Int) *big.Int

And returns the bitwise and of a and b (a & b in Go).

func Clear ¶

func Clear(a, b *big.Int) *big.Int

Clear returns the bitwise and not of a and b (a &^ b in Go).

func Len ¶

func Len(x uint64) int

Len returns the minimum number of bits required to represent x; the result is 0 for x == 0.

func OnesCount ¶

func OnesCount(x uint64) int

OnesCount returns the number of one bits ("population count") in x.

func Or ¶

func Or(a, b *big.Int) *big.Int

Or returns the bitwise or of a and b (a | b in Go).

func Reverse ¶

func Reverse(x uint64) uint64

Reverse returns the value of x with its bits in reversed order.

func ReverseBytes ¶

func ReverseBytes(x uint64) uint64

ReverseBytes returns the value of x with its bytes in reversed order.

func RotateLeft ¶

func RotateLeft(x uint64, k int) uint64

RotateLeft returns the value of x rotated left by (k mod UintSize) bits. To rotate x right by k bits, call RotateLeft(x, -k).

func Xor ¶

func Xor(a, b *big.Int) *big.Int

Xor returns the bitwise xor of a and b (a ^ b in Go).
