IEEE 754 does also specify operations and their behavior. E.g. section 5.1 (from 2008 edition):

> All conforming implementations of this standard shall provide the operations listed in this clause for all supported arithmetic formats, except as stated below. Each of the computational operations that return a numeric result specified by this standard shall be performed as if it first produced an intermediate result correct to infinite precision and with unbounded range, and then rounded that intermediate result, if necessary, to fit in the destination’s format (see 4 and 7).

Well the fact is that different hardware rounds it differently, so its the world we live in. My guess is that actually implementing something in hardware " to infinite precision and with unbounded range" might not be realistic.
