[CLN-list] confusion with cln::cl_F and cln::cl_R

[Joshua Friedman]

The program runs when I define "bigF = cln_R", but I get errors when I set
"bigF = cln_F"
I found that the exponential function only gives many digits of precision
when I use cln_F.
I am attaching my program and the out put is below:
