Both ints and floats represent real, rational values, but every operation in no way matches math. Associative? No. Commutative? No. Partially Ordered? No. Weakly Ordered? No. Symmetric? No. Reflexive? No. Antisymmetric? No. Nothing.

The only reasonable way to compare rationals is the decimal expansion of the string.

It’s not straightforward to compare numerical ordering using the decimal expansion.

Careful, someone is liable to throw this in an LLM prompt and get back code expanding the ASCII characters for string values like "1/346".

What exactly do you say is not commutative? This Wikipedia article claims that at least floating-point addition and multiplication are both commutative:

		it is for finite values, but because IEEE did some dumb things it isn't specified to be for NaN values (and on several architectures, isn't).
