Problem Solution:

Here, we will find the absolute value of a given number using the abs() function and print the result on the console screen.

Program/Source Code:

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

// Swift program to find the
// absolute value of a number

import Swift
import Foundation

var num:Double  =   -25.23
var res:Double  =   0.0

res = abs(num)

print("Result is: ",res)

Output:

Result is:  25.23

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

To use mathematics and some standard functions, we need to import the foundation package using the below statement,

import Foundation;

Here, we created two double type variables num, res initialized with "-25.23", "0.0". Then we found the absolute value of variable num using the abs() function and printed the result on the console screen.
