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".
