This script is one of the first I did. Therefore, it may be a little rough but should still be a good learning tool. Unlike a lot of calculators you will see on the internet, this one has an accuracy to 7 decimal places with 8 being displayed. Here is a simple test that you can try on other calculators that you see. Try adding 0.3 to 0.6. You may be surprised to find out that most do not result in the right answer of 0.9 but instead something like 0.89999999.
