You mean like having pi to any desired number of digits? As far as I
know, there is no intrinsic support for this in any FORTRAN (or C, for
that matter) compiler.

There are arbitrary precision libraries like libmpfr that seem like
they do want you want. I have no idea if any have FORTRAN bindings,
but you could write wrapper code in C for the needed functions using,
for instance, cfortran.
