This worries me. I know it is true mathamatically, but experience tells me trusting floats is a recipe for disaster. A approximate equal operator is safer.
Floats are such a leaky abstraction it is in my opinion better students know this early on.
1/3

Emphasis mine. WTF, author.
But the Java sample below saying "this is false" implies that floats are a problem that is being avoided. The only reasonable solution is rationals... right?
If you go into the editor/REPL (https://code.pyret.org/editor) and enter 1/3, you'll see that it gets rendered as 0.3 repeating (with a bar, not some arbitrary rounding) or if you click on it, directly as 1/3.
