Question

Write a function template that accepts an argument and returns its absolute value. The absolute value of a number is its value with no sign. For example, the absolute value of -5 is 5, and the absolute value of 2 is 2. Test the template in a simple driver program being sure to send the template short, int, double, float, and long data values.

Answer 1

Answer:

The function in Java is as follows:

public static double func(double num){

       num = Math.abs(num);

       return num;

   }

Explanation:

This defines the function

public static double func(double num){

This determines the absolute function of num

       num = Math.abs(num);

This returns the calculated absolute value

       return num;

   }
