Finding Cube Root of Specified Number in Golang
  • Last Updated : 01 Apr, 2020

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 cube root of the specified number with the help of Cbrt() 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 Cbrt() function.

Syntax:

func Cbrt(y float64) float64
  • If you pass +Inf or -Inf in this function, then this function will return +Inf or -Inf.
  • If you pass 0 in this function, then this function will return 0.
  • If you pass NaN(not-a-number) in this function, then this function will return NaN.

Example 1:




// Golang program to illustrate how to find
// the cube root of the given number
  
package main
  
import (
    "fmt"
    "math"
)
  
// Main function
func main() {
  
    // Finding the cube root
    // of the given value
    // Using Cbrt() function
    res_1 := math.Cbrt(3)
    res_2 := math.Cbrt(math.Inf(-3))
    res_3 := math.Cbrt(0)
    res_4 := math.Cbrt(math.NaN())
  
    // Displaying the result
    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)
}

Output:

Result 1: 1.4
Result 2: -Inf
Result 3: 0.0
Result 4: NaN

Example 2:




// Golang program to illustrate how to find
// the cube root of the given number
  
package main
  
import (
    "fmt"
    "math"
)
  
// Main function
func main() {
  
    // Finding cube root 
    // of the given number
    nvalue_1 := math.Cbrt(3)
    nvalue_2 := math.Cbrt(-7)
  
    // Sum of the given values
    res := nvalue_1 + nvalue_2
  
    // Displaying results
    fmt.Printf("%.1f + %.1f = %.1f",
            nvalue_1, nvalue_2, res)
  
}

Output:

1.4 + -1.9 = -0.5
