GoLang – Find Inverse Hyperbolic – Atanh() Function – Examples & Explanation

The syntax of Atanh() function in Go Language is:

func Atanh(x float64) float64

Note: float64 is a data type in Go language which has IEEE-754 64-bit floating-point numbers.
Special cases are:
Atanh(1) = +Inf
Atanh(±0) = ±0
Atanh(-1) = -Inf
Atanh(x) = NaN if x < -1 or x > 1
Atanh(NaN) = NaN

x – Where x is any Valid float64 Input value. This parameter is required.

If the x parameter is not a number (numeric value) Atanh() function returns an error .
If there is no argument (x – input value) passes to the function, then the compiler will produce an error.

Atanh() function will returns the inverse hyperbolic tangent of the given input(x – parameter).

pckage main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Atanh(-1)
	fmt.Println(x)
}

Output:
-Inf

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Atanh(0)
	fmt.Println(x)
}

Output:
0

package main

import "fmt"
import "math"

func main() {
	var x float64
	x = math.Atanh(8)
	fmt.Println(x)
}

Output:
NaN
