# Module Stdlib.Int

    module Int: Int

## Integers

    type t = int

The type for integer values.

    val zero : int

`zero` is the integer `0`.

    val one : int

`one` is the integer `1`.

    val minus_one : int

`minus_one` is the integer `-1`.

    val neg : int -> int

`neg x` is `~-x`.

    val add : int -> int -> int

`add x y` is the addition `x + y`.

    val sub : int -> int -> int

`sub x y` is the subtraction `x - y`.

    val mul : int -> int -> int

`mul x y` is the multiplication `x * y`.

    val div : int -> int -> int

`div x y` is the division `x / y`. See `(/)` for details.

    val rem : int -> int -> int

`rem x y` is the remainder `x mod y`. See `(mod)` for details.

    val succ : int -> int

`succ x` is `add x 1`.

    val pred : int -> int

`pred x` is `sub x 1`.

    val abs : int -> int

`abs x` is the absolute value of `x`. That is `x` if `x` is positive and `neg x` if `x` is negative. Warning. This may be negative if the argument is `Int.min_int`.

    val max_int : int

`max_int` is the greatest representable integer, `2{^[Sys.int_size - 1]} - 1`.

    val min_int : int

`min_int` is the smallest representable integer, `-2{^[Sys.int_size - 1]}`.

    val logand : int -> int -> int

`logand x y` is the bitwise logical and of `x` and `y`.

    val logor : int -> int -> int

`logor x y` is the bitwise logical or of `x` and `y`.

    val logxor : int -> int -> int

`logxor x y` is the bitwise logical exclusive or of `x` and `y`.

    val lognot : int -> int

`lognot x` is the bitwise logical negation of `x`.

    val shift_left : int -> int -> int

`shift_left x n` shifts `x` to the left by `n` bits. The result is unspecified if `n < 0` or `n >` `Sys.int_size`.

    val shift_right : int -> int -> int

`shift_right x n` shifts `x` to the right by `n` bits. This is an arithmetic shift: the sign bit of `x` is replicated and inserted in the vacated bits. The result is unspecified if `n < 0` or `n >` `Sys.int_size`.

    val shift_right_logical : int -> int -> int

`shift_right x n` shifts `x` to the right by `n` bits. This is a logical shift: zeroes are inserted in the vacated bits regardless of the sign of `x`. The result is unspecified if `n < 0` or `n >` `Sys.int_size`.

## Predicates and comparisons

    val equal : int -> int -> bool

`equal x y` is `true` iff `x = y`.

    val compare : int -> int -> int

`compare x y` is `compare` `x y` but more efficient.

## Converting

    val to_float : int -> float

`to_float x` is `x` as a floating point number.

    val of_float : float -> int

`of_float x` truncates `x` to an integer. The result is unspecified if the argument is `nan` or falls outside the range of representable integers.

    val to_string : int -> string

`to_string x` is the written representation of `x` in decimal.
