Overview

math package of GO provides a Pow method that can be used to calculate x to the power y.

Below is the signature of the function. It takes input as two float arguments and returns a float

func Pow(x, y float64) float64

The same function can also be used to calculate the square or cube of a number. Just pass the second argument y as 2 in case of square and 3 in case of cube

Code

package main
import (
"fmt"
"math"
)
func main() {
//Power for integers
res := math.Pow(2, 10)
fmt.Println(res)
//Power for float
res = math.Pow(1.5, 2)
fmt.Println(res)
//Anything to power 0 is 1
res = math.Pow(3, 0)
fmt.Println(res)
}

Output:
