The operations on floating point numbers do not behave like rational numbers. Floating point 1.0/3.0 is not equal to the rational 1/3. It's the same up to a margin of error, yes, but that's where the emulation part comes in. It would also be fair to say that floating point numbers are "emulated rationals".

Floating point numbers behave like rational numbers _with denominators that are powers of 2 only_.
