Multiplication Big Numbers

The purpose of this application is to test the range of the maximum and the minimum of Double Numeric Data Types of Java type programming. This app will do some multiplication that can produce the result between double positive range between 4.9E-324 to 1.7976931348623157E308 and double negative range between -1.7976931348623157e308 to -4.9e-324. Notice that, this apps can be typed with letter e or E to represent power of 10. That is why very useful for big numbers.
Feel free to test the result between the range, if more than that the results will be displayed infinity of 0.0 is too small.
By making this application it will motivate me to create more program that uses a big numbers as well.

Thank you for your support.
