when floats go into exponential notation then they don't save into files correctly and then it can't be parsed

[eeeeaaii]

Basically the Float nex is storing numbers as a string representation rather than a JS number object internally. That means that arithmetic with large numbers doesn't even work.

It needs to store the numbers internally as actual numbers, and also, the parser needs to be updated to handle large numbers (it's just the letter e I think).
