In Go, the math package provides a Sqrt function that can be used to get the square root of a number. Here's an example code that demonstrates how to use the math.Sqrt function:
package main
import (
"fmt"
"math"
)
func main() {
// Get the square root of a number
x := 16.0
y := math.Sqrt(x)
fmt.Printf("The square root of %f is %f\n", x, y)
}
In this example, we first import the math package, which contains the Sqrt function. We then declare a variable x and assign it the value 16.0. We then call the math.Sqrt function with x as an argument and assign the result to y.
Finally, we use the fmt.Printf function to print the result y along with the original number x.
The output of this program would be:
The square root of 16.000000 is 4.000000
This indicates that the square root of 16 is 4.
