NAME
Int - Integer values.
Module
Module Int

Module Int
: sig end
Integer values.
Integers are Sys.int_size bits wide and use two's complement represen-
tation. 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 unspeci-
fied 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.
