A quick Reverse Polish Notation Calculator. Please check the wikipedia page below in the notes if you don't know what that is (though I may eventually write up a tutorial). This has probably been done before, but I wanted to make my own. Currently, there is support for the 4 basic math operators, and all the scientific operators included in Scratch. ceil, floor, rand and mod are have also been implemented. It is whitespace delimited with no error handling, so invalid inputs will take up space on the stack. I'm hoping to use this implementation to preform more complex mathematical operations when Scratch's infix notation gets too cluttered for my purposes.
