This is an observation I have just made about IDL.

When you compile a FORTRAN program, you can specify G_floating
implementations of REAL*8. This extends the range of numbers to +-0.56D308.
(For default D_floating, the maximum number allowed is 0.29D38.)

On the other hand, IDL has no option for the larger G_floating numbers. This
makes for problems when you convert a "G_floating REAL*8 " FORTRAN program to
IDL.
