1. THE DOUBLE VARIABLE The double variable can hold very large (or small) numbers. The maximum and minimum values are 17 followed by 307 zero’s.

2. The double variable is also used to hold floating point values. A floating point value is one like 8.7, 12.5, 10.1. In other words, it has a "point something" at the end. If you try to store a floating point value in an int variable, NetBeans will underline the faulty code. If you try to run the program, the compiler will throw up an error message. Let's get some practice using doubles. Change the int from your previous code to double. So change this:your previous code int first_number, second_number, answer; to this: double first_number, second_number, answer; Now change the values being stored: first_number = 10.5; second_number = 20.8;

3. Leave the rest of the program as it is. Your coding window should look like this: Run your program again. The output window should look like this: Try changing the values stored in first_number and second_number. Use any values you like. Run your program and see what happens.
