Atanh()

The Atanh() function takes a float64 argument representing the angle whose inverse hyperbolic tangent value is to be returned. It returns this inverse hyperbolic tangent as a float64 value that can range from negative infinity to positive infinity.

Syntax

result := math.Atanh(x)

Where x represents the angle whose inverse hyperbolic tangent value is to be returned, and result is the inverse hyperbolic tangent of x. Some special exceptions include:

• Atanh(-1) equals -Inf
• Atanh(1) equals +Inf

Example

The following code calculates the arctangent and prints out the result:

package main

import (
  "fmt"
  "math"
  )

func main() {

  fmt.Println(math.Atanh(0.5))
  fmt.Println(math.Atanh(math.NaN()))

}

The output will be:

0.5493061443340548
NaN
