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
type t = int
val zero : t

zero is the integer 0.

  • since 3.0
val one : t

one is the integer 1.

  • since 3.0
val minus_one : t

minus_one is the integer -1.

  • since 3.0
val add : t -> t -> t

add x y is x + y.

  • since 3.0
val sub : t -> t -> t

sub x y is x - y.

  • since 3.0
val mul : t -> t -> t

mul x y is x * y.

  • since 3.0
val div : t -> t -> t

div x y is x / y

  • since 3.0
val succ : t -> t

succ x is x + 1.

  • since 3.0
val pred : t -> t

pred x is x - 1.

  • since 3.0
val abs : t -> t

abs x is the absolute value of x. It is x if x is positive and neg x otherwise.

  • since 3.0
val max_int : t

max_int is the maximum integer.

  • since 3.0
val min_int : t

min_int is the minimum integer.

  • since 3.0
val compare : t -> t -> int

compare x y is the comparison function for integers with the same specification as Stdlib.compare.

val equal : t -> t -> bool

equal x y is true iff x and y are equal. Equality function for integers.

val hash : t -> int

hash x computes the hash of x.

val sign : t -> int

sign x return 0 if x = 0, -1 if x < 0 and 1 if x > 0. Same as compare x 0.

val neg : t -> t

neg x is - x. Unary negation.

  • since 0.5
val pow : t -> t -> t

pow base exponent returns base raised to the power of exponent. pow x y = x^y for positive integers x and y. Raises Invalid_argument if x = y = 0 or y < 0.

  • since 0.11
val floor_div : t -> t -> t

floor_div x n is integer division rounding towards negative infinity. It satisfies x = m * floor_div x n + rem x n.

  • since 1.2
val rem : t -> t -> t

rem x n is the remainder of dividing x by n, with the same sign as n.

  • since 1.2
type 'a printer = Stdlib.Format.formatter -> 'a -> unit
type 'a random_gen = Stdlib.Random.State.t -> 'a
type 'a iter = ('a -> unit) -> unit
val random : int -> t random_gen
val random_small : t random_gen
val random_range : int -> int -> t random_gen
val pp : t printer

pp ppf x prints the integer x on ppf.

val to_float : t -> float

to_float is the same as float_of_int

  • since 3.0
val to_string : t -> string

to_string x returns the string representation of the integer x, in signed decimal.

  • since 0.13
val of_string : string -> t option

of_string s converts the given string s into an integer. Safe version of of_string_exn.

  • since 0.13
val of_string_exn : string -> t

of_string_exn s converts the given string s to an integer. Alias to int_of_string.

  • raises Failure

    in case of failure.

  • since 3.0
val of_float : float -> t

of_float x converts the given floating-point number x to an integer. Alias to int_of_float.

  • since 3.0
val pp_binary : t printer

pp_binary ppf x prints x on ppf. Print as "0b00101010".

  • since 0.20
val to_string_binary : t -> string

to_string_binary x returns the string representation of the integer x, in binary.

  • since 0.20
val min : t -> t -> t

min x y returns the minimum of the two integers x and y.

  • since 0.17
val max : t -> t -> t

max x y returns the maximum of the two integers x and y.

  • since 0.17
val range_by : step:t -> t -> t -> t iter

range_by ~step i j iterates on integers from i to j included, where the difference between successive elements is step. Use a negative step for a decreasing list.

  • raises Invalid_argument

    if step=0.

  • since 1.2
val range : t -> t -> t iter

range i j iterates on integers from i to j included . It works both for decreasing and increasing ranges.

  • since 1.2
val range' : t -> t -> t iter

range' i j is like range but the second bound j is excluded. For instance range' 0 5 = Iter.of_list [0;1;2;3;4].
