How to Find the Square Root of a Number in Golang

To find the square root of a number in Golang:

1. Import the package math in the golang program
2. Use the Sqrt() function, it takes a number as an input parameter.
3. It returns the square root of a number.

Syntax

func Sqrt(x float64) float64

Where,

Parameter: x as input number of type float64

Return: It returns the square root of x of type float64

Special Cases for Square Root are:

Sqrt(+Inf) = +Inf
Sqrt(±0) = ±0
Sqrt(x < 0) = NaN
Sqrt(NaN) = NaN

In this article, we will discuss how to calculate the square root of a number in golang.

How to Calculate the Square Root of a Number in Golang

To calculate the square root of a number in golang, you can use the Sqrt() method of the math package.

package main

import (
	"fmt"
	"math"
)

// Main function
func main() {

	// Finding square root of the given number
	// Using Sqrt() function
	ans1 := math.Sqrt(0)
	fmt.Printf("Square Root of 0: %.1f", ans1)

	ans2 := math.Sqrt(4)
	fmt.Printf("\nSquare Root of 4: %.1f", ans2)

	ans3 := math.Sqrt(math.NaN())
	fmt.Printf("\nSquare Root of NAN: %.1f", ans3)

	ans4 := math.Sqrt(-64)
	fmt.Printf("\nSquare Root of Negative Number: %.1f", ans4)

	ans5 := math.Sqrt(math.Inf(1))
	fmt.Printf("\nSquare Root of Infinity: %.1f", ans5)

}

Output

Square Root of 0: 0.0
Square Root of 4: 2.0
Square Root of NAN: NaN
Square Root of Negative Number: NaN
Square Root of Infinity: +Inf

In the above golang program, we import the math package and use the Sqrt function to get the square root for a given number.

Conclusion

I hope the above article helped you to find the square root of a given number in golang.
