Cosh

Returns the hyperbolic cosine.

Module: Math

Signature

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

Parameters

Name	Type	Description
x	float64 / float32	Any value.

Returns

The hyperbolic cosine of x, always at least 1.0. Cosh(±Inf) is +Inf. Cosh overflows to +Inf for large |x|. A NaN argument propagates.

Example

import Math::Cosh;

let a = Cosh(0.0); // 1.0
let b = Cosh(1.0); // 1.5430806348152437
