Things I learned yesterday and today.

Python doesn't understand quadruple-precision real numbers. f2py will happily compile Fortran code containing real(16)s into a form that Python can talk to, but Python will segfault as soon as it receives one of those real(16)s.

Also, Fortran's built-in fraction function doesn't do what I thought it did.

Hold on, f2py CAN make Fortran functions comprehensible to Python‽ I DON'T have to use subroutines‽ Fortran syntax is just incredibly FUSSY‽
