Printing the absolute value for an integer number in Golang

In this program, we will create a variable of integer type initialize with -25, and then print the absolute value of the variable on the console screen.

Golang code to print the absolute value for an integer number

The source code to print the absolute value for an integer number is given below. The given program is compiled and executed successfully.

// Golang program to print the absolute value for an integer number

package main
import "fmt"

func GetIntAbs(val int64) int64 {
	if val < 0 {
		return -val
	}
	return val
}

func main() {
    var val int64 = -25
   
    fmt.Printf("Absolute value of %d is %d",val,GetIntAbs(val)) 
}

Output

Absolute value of -25 is 25

Explanation

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a functions related to the fmt package.

As we know that, there is no predefined function to get the absolute value for an integer number then we created a user define function to get the absolute value of an integer number. Here, we created a variable value, which is initialized with -25. After that, we get the absolute value using user define function GetIntAbs() and print the result on the console screen.
