fortran90 – CEILING and FLOOR function in Fortran – aren’t …
CEILING and FLOOR do return integer results. However, you are not printing those results: you are printing the variables celix and floorx which are of real type.. Those variables are real because of implicit typing. Contrast this with nintx which is indeed an integer variable.. List-directed output (the write(*,*) part) has as natural result formatting the real variables as you see.

F2c converts Fortran 77 source code in files with names ending in `.f’ or `.F’ to C (or C++) source files in the current directory, with `.c’ substituted for the final `.f’ or `.F’. If no Fortran files are named, f2c reads Fortran from standard input and writes C on standard output.
How to link a gfortran static library? | Qt Forum
The name f_analysis_x in fortran resolves to f_analysis_x_ in C terms, so if the function’s called myfunc in fortran, it should be declared as myfunc_ in C (yes, C-linkage is required). Finally, fortran doesn’t know what const is, so don’t lie to your C compiler. Another thing may be that you have a static libgfortran and a dynamic one in your …
