NAME
       Int32 - 32-bit integers.

Module
       Module	Int32

Documentation
       Module Int32
	: sig end

       32-bit integers.

       This  module provides operations	on the type int32 of signed 32-bit in-
       tegers.	Unlike the built-in int	type, the type int32 is	guaranteed  to
       be  exactly  32-bit  wide  on all platforms.  All arithmetic operations
       over int32 are taken modulo 2^{32.

       Performance notice: values of type int32	occupy more memory space  than
       values  of  type	int , and arithmetic operations	on int32 are generally
       slower than those on int	.  Use int32 only  when	 the  application  re-
       quires exact 32-bit arithmetic.

       val zero	: int32

       The 32-bit integer 0.

       val one : int32

       The 32-bit integer 1.

       val minus_one : int32

       The 32-bit integer -1.

       val neg : int32 -> int32

       Unary negation.

       val add : int32 -> int32	-> int32

       Addition.

       val sub : int32 -> int32	-> int32

       Subtraction.

       val mul : int32 -> int32	-> int32

       Multiplication.

       val div : int32 -> int32	-> int32

       Integer	division.   Raise  Division_by_zero  if	the second argument is
       zero.  This division rounds the real quotient of	its arguments  towards
       zero, as	specified for Pervasives.(/) .

       val rem : int32 -> int32	-> int32

       Integer	remainder.  If y is not	zero, the result of Int32.rem x	y sat-
       isfies the following property: x	= Int32.add (Int32.mul (Int32.div x y)
       y)  (Int32.rem x	y) .  If y = 0 , Int32.rem x y raises Division_by_zero
       .

       val succ	: int32	-> int32

       Successor.  Int32.succ x	is Int32.add x Int32.one .

       val pred	: int32	-> int32

       Predecessor.  Int32.pred	x is Int32.sub x Int32.one .

       val abs : int32 -> int32

       Return the absolute value of its	argument.

       val max_int : int32

       The greatest representable 32-bit integer, 2^{31	- 1.

       val min_int : int32

       The smallest representable 32-bit integer, -2^{31.

       val logand : int32 -> int32 -> int32

       Bitwise logical and.

       val logor : int32 -> int32 -> int32

       Bitwise logical or.

       val logxor : int32 -> int32 -> int32

       Bitwise logical exclusive or.

       val lognot : int32 -> int32

       Bitwise logical negation

       val shift_left :	int32 -> int ->	int32

       Int32.shift_left	x y shifts x to	the left by y bits.  The result	is un-
       specified if y <	0 or y >= 32 .

       val shift_right : int32 -> int -> int32

       Int32.shift_right  x  y	shifts	x  to the right	by y bits.  This is an
       arithmetic shift: the sign bit of x is replicated and inserted  in  the
       vacated bits.  The result is unspecified	if y < 0 or y >= 32 .

       val shift_right_logical : int32 -> int -> int32

       Int32.shift_right_logical x y shifts x to the right by y	bits.  This is
       a logical shift:	zeroes are inserted in the vacated bits	regardless  of
       the sign	of x .	The result is unspecified if y < 0 or y	>= 32 .

       val of_int : int	-> int32

       Convert	the  given integer (type int ) to a 32-bit integer (type int32
       ).

       val to_int : int32 -> int

       Convert the given 32-bit	integer	(type int32 ) to an integer (type  int
       ).  On 32-bit platforms,	the 32-bit integer is taken modulo 2^{31, i.e.
       the high-order bit is lost during the conversion.  On 64-bit platforms,
       the conversion is exact.

       val of_float : float -> int32

       Convert the given floating-point	number to a 32-bit integer, discarding
       the fractional part (truncate towards 0).  The result of	the conversion
       is  undefined  if,  after truncation, the number	is outside the range [
       Int32.min_int , Int32.max_int ].

       val to_float : int32 -> float

       Convert the given 32-bit	integer	to a floating-point number.

       val of_string : string -> int32

       Convert the given string	to a 32-bit integer.  The string  is  read  in
       decimal	(by  default) or in hexadecimal, octal or binary if the	string
       begins with 0x ,	0o or 0b respectively.	Raise Failure int_of_string if
       the given string	is not a valid representation of an integer, or	if the
       integer represented exceeds the range of	integers representable in type
       int32 .

       val to_string : int32 ->	string

       Return the string representation	of its argument, in signed decimal.

       val bits_of_float : float -> int32

       Return  the internal representation of the given	float according	to the
       IEEE 754	floating-point 'single format' bit layout.  Bit	31 of the  re-
       sult represents the sign	of the float; bits 30 to 23 represent the (bi-
       ased) exponent; bits 22 to 0 represent the mantissa.

       val float_of_bits : int32 -> float

       Return the floating-point number	whose internal representation, accord-
       ing  to	the IEEE 754 floating-point 'single format' bit	layout,	is the
       given int32 .

       type t =	int32

       An alias	for the	type of	32-bit integers.

       val compare : t -> t -> int

       The comparison function for 32-bit integers, with the  same  specifica-
       tion  as	 Pervasives.compare  .	 Along with the	type t , this function
       compare allows the module Int32 to be passed as argument	to  the	 func-
       tors Set.Make and Map.Make .

       === Deprecated functions	===

       val format : string -> int32 -> string

       Do not use this deprecated function.  Instead, used Printf.sprintf with
       a %l...	format.
