Round

Rounds to the nearest integer value.

Module: Math

Signature

func Round(x: float64) -> float64;
func Round(x: float32) -> float32;

Parameters

Name	Type	Description
x	float64 / float32	The value to round.

Returns

The nearest integer value to x, still represented as a floating-point number. A tie rounds away from zero: Round(2.5) is 3.0 and Round(-2.5) is -3.0. Infinities and NaNs pass through unchanged.

Example

import Math::Round;

let a = Round(2.5);  // 3.0
let b = Round(-2.5); // -3.0
let c = Round(2.4);  // 2.0
