Finding the Inverse Hyperbolic Tangent of Specified Number in Golang
Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You are allowed to find the inverse hyperbolic tangent of the specified number with the help of the Atanh() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Atanh() function.
Syntax:
func Atanh(y float64) float64
- If you pass 1 in this function, then this function will return +Inf.
- If you pass -1 in this function, then this function will return -Inf.
- If you pass -0 or +0 in this function, then this function will return -0 or +0.
- If you pass NaN in this function, then this function will return NaN.
- If y < -1 or y > 1, then this function will return NaN.
Example 1:
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Atanh(math.Pi / 4)
res_2 := math.Atanh(math.Inf(-3))
res_3 := math.Atanh(0)
res_4 := math.Atanh(math.NaN())
res_5 := math.Atanh(-1)
fmt.Printf( "Result 1: %.1f" , res_1)
fmt.Printf( "\nResult 2: %.1f" , res_2)
fmt.Printf( "\nResult 3: %.1f" , res_3)
fmt.Printf( "\nResult 4: %.1f" , res_4)
fmt.Printf( "\nResult 5: %.1f" , res_5)
}
|
Output:
Result 1: 1.1
Result 2: NaN
Result 3: 0.0
Result 4: NaN
Result 5: -Inf
Example 2:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Atanh(math.Pi / 3)
nvalue_2 := math.Atanh(math.Pi / 6)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.1f + %.1f = %.1f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
NaN + 0.6 = NaN
