Program/Source Code:

The source code to print the absolute value of the float number is given below. The given program is compiled and executed successfully.

// Golang program to print the 
// absolute value of float number.

package main
import "fmt"
import "math"

func main() {
    var val float64 = -19.25
    
    fmt.Printf("Absolute value of %f is %f",val,math.Abs(val)) 
}

Output:

Absolute value of -19.250000 is 19.250000

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 function related to the fmt package.

Here, we also included the math package to use math-related functions. Here, we used the Abs() function of the math package to find the absolute value of the specified float variable and print the result on the console screen.
