       Module Int
        : sig end

       Integer values.

       Integers  are  Sys.int_size  bits  wide  and  use  two's  complement  representation.  All
       operations are taken modulo 2^ Sys.int_size . They do not fail on overflow.

       Since 4.08

   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 if and only if x = y .

       val compare : int -> int -> int

       compare x y is compare x y but more efficient.

       val min : int -> int -> int

       Return the smaller of the two arguments.

       Since 4.13.0

       val max : int -> int -> int

       Return the greater of the two arguments.

       Since 4.13.0

   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.
