The trouble is that numerical intensive applications often need
efficient implementations.

If you require IEEE arithmetic, and you are on a machine whose hardware
does not support IEEE-754 (note: supports and not implements, since
IEEE-754 is a software standard), you have a choice of 1) implement the
whole standard in software and say bye-bye to efficiency, or 2) ignore
the standard and use the native floating-point, which is a failure of
the standardization.

The Ada model allows portable guaranteed bounds to inaccurracy, without
requiring any particular arithmetic model, and is therefore efficiently
implementable on any hardware. That was part of the requirements.
