Exp2

Returns 2 raised to a power.

Module: Math

Signature

func Exp2(x: float64) -> float64;
func Exp2(x: float32) -> float32;

Parameters

Name	Type	Description
x	float64 / float32	The exponent.

Returns

2^x, in the same precision as the argument. Exp2 overflows to +Inf for x >= 1024.0 and underflows to +0.0 for x < -1075.0. A NaN propagates.

Example

import Math::Exp2;

let a = Exp2(10.0); // 1024.0
let b = Exp2(-1.0); // 0.5
