# Module unsigned

This module implements basic arithmetic operators for unsigned integers. To discourage users from using `unsigned`, it's not part of `system`, but an extra import.

# Procs

    proc `not`[T](x: T): T {.magic: "BitnotI", noSideEffect.}

  computes the bitwise complement of the integer x.

    proc `shr`[T](x, y: T): T {.magic: "ShrI", noSideEffect.}

  computes the shift right operation of x and y.

    proc `shl`[T](x, y: T): T {.magic: "ShlI", noSideEffect.}

  computes the shift left operation of x and y.

    proc `and`[T](x, y: T): T {.magic: "BitandI", noSideEffect.}

  computes the bitwise and of numbers x and y.

    proc `or`[T](x, y: T): T {.magic: "BitorI", noSideEffect.}

  computes the bitwise or of numbers x and y.

    proc `xor`[T](x, y: T): T {.magic: "BitxorI", noSideEffect.}

  computes the bitwise xor of numbers x and y.

    proc `==`[T](x, y: T): bool {.magic: "EqI", noSideEffect.}

  Compares two unsigned integers for equality.

    proc `+`[T](x, y: T): T {.magic: "AddU", noSideEffect.}

  Binary + operator for unsigned integers.

    proc `-`[T](x, y: T): T {.magic: "SubU", noSideEffect.}

  Binary - operator for unsigned integers.

    proc `*`[T](x, y: T): T {.magic: "MulU", noSideEffect.}

  Binary * operator for unsigned integers.

    proc `div`[T](x, y: T): T {.magic: "DivU", noSideEffect.}

  computes the integer division. This is roughly the same as `floor(x/y)`.

    proc `mod`[T](x, y: T): T {.magic: "ModU", noSideEffect.}

  computes the integer modulo operation. This is the same as `x - (x div y) * y`.

    proc `<=`[T](x, y: T): bool {.magic: "LeU", noSideEffect.}

  Returns true iff `x <= y`.

    proc `<`[T](x, y: T): bool {.magic: "LtU", noSideEffect.}

  Returns true iff `unsigned(x) < unsigned(y)`.
