Ceil

Rounds up to the nearest integer value.

Module: Math

Signature

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

Parameters

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

Returns

The smallest integer value at or above x, still represented as a floating-point number. Ceil(-0.5) is -0.0 rather than 0.0 — truncation carries the sign of x across, and IEEE-754 asks for that sign to survive. A NaN passes through unchanged.

Example

import Math::Ceil;

let a = Ceil(3.2);  // 4.0
let b = Ceil(-3.7); // -3.0
