Fortran: handling integer values of size: ~700000000000

Question

Currently I\'m brushing up on my Fortran95 knowledge (don\'t ask why)...

I\'m running in to a problem though. How does one handle large integers, eg. the size of: ~7

Answer 1

There are a number of free arbitrary-precision libraries available for Fortran which would deal with this problem. FMLIB is one. Five or six more alternatives are linked from this page.
