Return value:

Log2() function in math package returns
the binary logarithm of num.

Example with code:

package main

import (
  "fmt"
  "math"
)

func main() {

  no := math.Log2(1.2)
  fmt.Println(no)

  no = math.Log2(2.3)
  fmt.Println(no)

  no = math.Log2(0.0)
  fmt.Println(no)

  no = math.Log2(-2.9)
  fmt.Println(no)
}

Output:

0.2630344058337938
1.2016338611696504
