Module `Frama_c_kernel.Int`

Extension of OCaml's Stdlib.Int module.

since 32.0-Germanium

include module type of 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 Stdlib.(/) for details.

val rem : int -> int -> int

rem x y is the remainder x mod y. See Stdlib.(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 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 Stdlib.compare x y but more efficient.

val min : int -> int -> int

Return the smaller of the two arguments.

since 4.13

val max : int -> int -> int

Return the greater of the two arguments.

since 4.13

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.

val seeded_hash : int -> int -> int

A seeded hash function for ints, with the same output value as Hashtbl.seeded_hash. This function allows this module to be passed as argument to the functor Hashtbl.MakeSeeded.

since 5.1

val hash : int -> int

An unseeded hash function for ints, with the same output value as Hashtbl.hash. This function allows this module to be passed as argument to the functor Hashtbl.Make.

since 5.1

val gcd : int -> int -> int

Compute the greatest common divisor of two ints.
