acosh()

The acosh() function is used to calculate the inverse hyperbolic cosine(arccosh) of a given number.

Syntax

acosh(x)

The function accepts one mandatory parameter x, which should be a numeric value greater than or equal to 1. The argument can be of Double and Float datatype.

Note: It returns the hyperbolic arccosine of the argument, which represents a real number.

Example

The example below demonstrates how to use acosh() to calculate the hyperbolic arccosine of 2.0.

import kotlin.math.acosh
fun main() {
    val x = 2.0
    val result = acosh(x)
    println(result)
}

The output will be:
