Exp

Returns e raised to a power.

Module: Math

Signature

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

Parameters

Name	Type	Description
x	float64 / float32	The exponent.

Returns

e^x, in the same precision as the argument. Exp overflows to +Inf for large positive x and underflows to +0.0 for large negative x. Exp(+Inf) is +Inf, Exp(-Inf) is +0.0, and a NaN propagates.

Example

import Math::Exp;

let a = Exp(1.0); // 2.718281828459045 (e)
let b = Exp(0.0); // 1.0
