math.Log2E Constant

The Log2E constant is an inbuilt constant of the math package which is used to get the base 2 logarithm of the mathematical constant e, approximately equal to 1.442. The math.Log2E constant is equivalent to 1/math.Ln2.

Syntax:

float64 math.Log2E

Parameter(s):

• None

Return Value:

The return type of math.Log2E constant is float64, it returns the base 2 logarithm of the mathematical constant e.

Example 1:

// Golang program to demonstrate the
// example of math.Log2E Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.Log2E is %T\n", math.Log2E)
	fmt.Println("Value of math.Log2E:", math.Log2E)
}

Output:

Type of math.Log2E is float64
Value of math.Log2E: 1.4426950408889634

Explanation:

In the above program, we imported the math package to use the math.Log2E constant, then printed the type and value of the math.Log2E constant.

Example 2:

// Golang program to demonstrate the
// example of math.Log2E Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of Log2E.
func getLog2E() float64 {
	return math.Log2E
}

func main() {
	fmt.Println("Value of math.Log2E:", getLog2E())
}

Output:

Value of math.Log2E: 1.4426950408889634
