Float

This module includes convenience methods for handling float types.

toInt

let toInt: float => int

Converts a given float to an int.

RES
Js.log(Belt.Float.toInt(1.0) === 1) /* true */

fromInt

let fromInt: int => float

Converts a given int to a float.

RES
Js.log(Belt.Float.fromInt(1) === 1.0) /* true */

fromString

let fromString: string => option<float>

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

RES
Js.log(Belt.Float.fromString("1.0") === Some(1.0)) /* true */

toString

let toString: float => string

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

RES
Js.log(Belt.Float.toString(1.0) === "1.0") /* true */

+

let (+): (float, float) => float

Addition of two float values. Can be opened in a module to avoid dot-notation (+.), however this yields a shadow warning (Warning number 44) in the default configuration.

RES
open Belt.Float
Js.log(2.0 + 2.0 === 4.0) /* true */

-

let (-): (float, float) => float

Subtraction of two float values. Can be opened in a module to avoid dot-notation (-.), however this yields a shadow warning (Warning number 44) in the default configuration.

RES
open Belt.Float
Js.log(2.0 - 1.0 === 1.0) /* true */

*

let (*): (float, float) => float

Multiplication of two float values. Can be opened in a module to avoid dot-notation (*.), however this yields a shadow warning (Warning number 44) in the default configuration.

RES
open Belt.Float
Js.log(2.0 * 2.0 === 4.0) /* true */

/

let (/): (float, float) => float

Division of two float values. Can be opened in a module to avoid dot-notation (/.), however this yields a shadow warning (Warning number 44) in the default configuration.

RES
open Belt.Float
Js.log(4.0 / 2.0 === 2.0) /* true */
