math.SqrtPi Constant

The SqrtPi constant is an inbuilt constant of the math package which is used to get the square root of the mathematical constant π, approximately equal to 1.77245385.

Syntax

float64 math.SqrtPi

Parameters

• None

Return Value

The return type of math.SqrtPi constant is float64, it returns the square root of the mathematical constant π.

Example 1

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

package main

import (
	"fmt"
	"math"
)

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

Output:

Type of math.SqrtPi is float64
Value of math.SqrtPi: 1.772453850905516

Explanation:

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

Example 2

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

package main

import (
	"fmt"
	"math"
)

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

func main() {
	fmt.Println("Value of math.SqrtPi:", getSqrtPi())
}

Output:

Value of math.SqrtPi: 1.772453850905516
