Quadruple precision

[sudhanvalalit]

I tried to convert the code from double precision to quadruple precision, and the code compiles well. However, while execution, it fails to read nets3 and nets4 files. Is there a proper way to read/write binary datafiles in quadruple precision?

Your best bet is probably to read/write nets3 and nets4 as double precision and then convert to quad.
I don't know how well quad-precision is supported by Fortran I/O.

Thanks for a quick response, let me try that and get back to you.
