Hello Bill,
Seems to me the only use is to
preserve a few more bits in intermediate computations.
There are some cases where you simply want to keep as much precision
as you can. In those cases variable precision floats aren't any
better of a solution as you would just turn them up as far as you can
without unacceptable cost elsewhere.
So what's the advice you would you give to Joe coder about when to use
'real'?
If you have no special reason to use float or double and are not IO or memory
space bound, use real. Every machine I know the details of will use it in
the FPU so the only general advantage to not using it is IO speed and data
size.
