I have to operate with some sums of very large integers. I know there is available a GMP Fortran library but I have never use it. Apparently, you have to link a static library when compiling the original code, but other than that I could not find any documentation about how it is used in Fortran. Do you know some information you can provide me as to how a regular code should be modified to be used along this GMP library?
Many thanks for the help.
