Hello,

Well, I run my code on intel visual fortran 2010 and it worked perfect, but while running it on Gnu compiler fortran 95 the results are NaN.
I really want to know what would be the difference.

Thanks

Hi!
Are you trying to localize place where NaN result is appears first time?
You can use IsNan function (http://gcc.gnu.org/onlinedocs/gfortran/ISNAN.html) to verifying;
