Float
This module includes convenience methods for handling float
types.
toInt
RElet toInt: float => int;
Converts a given float
to an int
.
REJs.log(Belt.Float.toInt(1.0) === 1); /* true */
fromInt
RElet fromInt: int => float;
Converts a given int
to a float
.
REJs.log(Belt.Float.fromInt(1) === 1.0); /* true */
fromString
RElet fromString: string => option(float);
Converts a given string
to a float
. Returns Some(float)
when the input is a number, None
otherwise.
REJs.log(Belt.Float.fromString("1.0") === Some(1.0)); /* true */
toString
RElet toString: float => string;
Converts a given float
to a string
. Uses the JavaScript String
constructor under the hood.
REJs.log(Belt.Float.toString(1.0) === "1.0"); /* true */
+
RElet (+): (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.
REopen Belt.Float;
Js.log(2.0 + 2.0 === 4.0); /* true */
-
RElet (-): (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.
REopen Belt.Float;
Js.log(2.0 - 1.0 === 1.0); /* true */
*
RElet ( * ): (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.
REopen Belt.Float;
Js.log(2.0 * 2.0 === 4.0); /* true */
/
RElet (/): (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.
REopen Belt.Float;
Js.log(4.0 / 2.0 === 2.0); /* true */
