Finding Cube Root 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 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:
Go
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Cbrt( 3 )
res_2 := math.Cbrt(math.Inf(- 3 ))
res_3 := math.Cbrt( 0 )
res_4 := math.Cbrt(math.NaN())
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:
Go
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Cbrt( 3 )
nvalue_2 := math.Cbrt(- 7 )
res := nvalue_1 + nvalue_2
fmt.Printf( "%.1f + %.1f = %.1f" ,
nvalue_1, nvalue_2, res)
}
