Waaaay less magic than Javascript. Looks like the rules are described here. Two kinds of numbers: exact and rough. Unless you use trig functions it will all be exact. https://www.pyret.org/docs/latest/numbers.html

Fun fact about Javascript: there are string and number constants x, y, and z, such that `x < y` and `y < z` and `z < x`. No NaN shenanigans, just regular small strings and numbers. Hint: it involves a string containing digits that starts with "0", thus sometimes getting implicitly coerced to octal.

Think about what this means for sorting!
