Overview

Package complement implements conversion from one and two's complement numbers to their native representation.

Functions

func Ones

func Ones(b byte) int8

Ones parses an 8-bit one's complement number into a native integer. The returned value has range -127 through 127 (one's complement has both positive and negative 0).

func Twos

func Twos(bigEndian [2]byte, bits uint8) int16

Twos parses two's complement numbers of up to 16 bits into a native integer. The input is two bytes in big-endian order, and the number of bits the binary representation is expected to be (0 through 16). More significant bits above this must be 0, e.g. Twos([...]byte{0b000000xx, 0bxxxxxxxx}, 10).
