Why don't we switch to C like floating pointed arithmetic instead of automatic expansion to reals?

There are cases where doing things at higher precision results in double 
rounding and a less accurate result. But I am pretty sure there are far fewer of 
those cases compared to routine computations that get a more accurate result 
with more precision.

If that wasn't true, we wouldn't ever need double precision.
