math.Ln2 Constant

The Ln2 constant is an inbuilt constant of the math package which is used to get the natural logarithm of 2, approximately equal to 0.693.

Syntax:

float64 math.Ln2

Parameter(s):

• None

Return Value:

The return type of math.Ln2 constant is float64, it returns the natural logarithm of 2.

Example 1:

// Golang program to demonstrate the
// example of math.Ln2 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.Ln2 is %T\n", math.Ln2)
	fmt.Println("Value of math.Ln2:", math.Ln2)
}

Output:

Type of math.Ln2 is float64
Value of math.Ln2: 0.6931471805599453

Explanation:

In the above program, we imported the math package to use the math.Ln2 constant, then printed the type and value of the math.Ln2 constant.

Example 2:

// Golang program to demonstrate the
// example of math.Ln2 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of Ln2.
func getLn2() float64 {
	return math.Ln2
}

func main() {
	fmt.Println("Value of math.Ln2:", getLn2())
}

Output:

Value of math.Ln2: 0.6931471805599453
