I've looked at Pascal, but never Ada.  My own language actually takes
some cues from Pascal's way of maintaining data integrity in the
presence of errant code, but still relaxes everything so you can still
truly shoot your program in its figurative foot.

C and C++ can often do this as well as the CPUs that exist are often
either truly IEEE-754 compliant, or have the ability to be so (such as
with x86 where you must do an intermediate store and re-load to have
appropriate (legal IEEE-754) rounding).
