    type my_very_precise_type is digits <N>;

where <N> is the number of digits of precision you need.  Be aware, however,
that few compilers support float types of precision greater than 15 digits.

If you have an application that depends on floating-point calculations of
very high precision, be especially careful in numerical analysis, design,
and testing.  Don't accept vendor's claims that their numerical libraries
perform correctly; test them in computations that are required in your
application.
