Int

This module includes convenience methods for handling int types.

let toFloat: int => float;

Converts a given int to a float.

RE
Js.log(Belt.Int.toFloat(1) === 1.0); /* true */

let fromFloat: float => int;

Converts a given float to an int.

RE
Js.log(Belt.Int.fromFloat(1.0) === 1); /* true */

let fromString: string => option(int);

Converts a given string to an int. Returns Some(int) when the input is a number, None otherwise.

RE
Js.log(Belt.Int.fromString("1") === Some(1)); /* true */

let toString: int => string;

Converts a given int to a string. Uses the JavaScript String constructor under the hood.

RE
Js.log(Belt.Int.toString(1) === "1"); /* true */

let (+): (int, int) => int;

Addition of two int values. Same as the addition from Pervasives.

RE
open Belt.Int;
Js.log(2 + 2 === 4); /* true */

let (-): (int, int) => int;

Subtraction of two int values. Same as the subtraction from Pervasives.

RE
open Belt.Int;
Js.log(2 - 1 === 1); /* true */

let ( * ): (int, int) => int;

Multiplication of two int values. Same as the multiplication from Pervasives.

RE
open Belt.Int;
Js.log(2 * 2 === 4); /* true */

let (/): (int, int) => int;

Division of two int values. Same as the division from Pervasives.

RE
open Belt.Int;
Js.log(4 / 2 === 2); /* true */
