math.Sqrt2 Constant

The Sqrt2 constant is an inbuilt constant of the math package which is used to get the square root of 2, approximately equal to 1.414.

Syntax

float64 math.Sqrt2

Parameters

• None

Return Value

The return type of math.Sqrt2 constant is float64, it returns the square root of 2.

Example 1

// Golang program to demonstrate the
// example of math.Sqrt2 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.Sqrt2 is %T\n", math.Sqrt2)
	fmt.Println("Value of math.Sqrt2:", math.Sqrt2)
}

Output:

Type of math.Sqrt2 is float64
Value of math.Sqrt2: 1.4142135623730951

Explanation:

In the above program, we imported the math package to use the math.Sqrt2 constant, then printed the type and value of the math.Sqrt2 constant.

Example 2

// Golang program to demonstrate the
// example of math.Sqrt2 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to return 
// the value of Sqrt2.
func getSqrt2() float64 {
	return math.Sqrt2
}

func main() {
	fmt.Println("Value of math.Sqrt2:", getSqrt2())
}

Output:

Value of math.Sqrt2: 1.4142135623730951
