DON'T USE THIS, PLEASE. it's EXTREMELY inefficient and you can't even add numbers properly. (or well, adding seems to be multiplying) Please use another BigNum engine such as Challage Accepted v2.1 by @yoreni (https://scratch.mit.edu/projects/314239008/, goes to e1.79e308), or engines by @Patcail such as break_eternity.sb3 (https://scratch.mit.edu/projects/335064418/, goes to 10^^1.79e308)
goes to ee308, can't use functions tho, and can't easily make more variables
