Pow()

The Pow() function returns the base x raised to the power y. The math library must be imported in order to use this function.

Syntax

result := math.Pow(x, y)

Where result is the value of x raised to the power y, returned as a float64, except under the following circumstances:

• If y is 0 or x is 1, the result is always 1.
• If either x or y is NaN, the result is NaN.
• If x is 0, the result depends on the sign and type (odd or not) of y. It can be +Inf, -Inf, or 0.
• If x is +Inf or -Inf, the result depends on the sign of y and can be +Inf, -Inf, or 0.
• If x is a finite negative number and y is a finite non-integer, the result is NaN.

Example

The following example calculates the result of base raised to the power exponent and prints out the result:

package main

import (
  "fmt"
  "math"
)

func main() {
  c := math.Pow(2, 3)
  fmt.Printf("%.1f", c)
}

The output will be:

8.0
