Arbitrary precision integer arithmetic: ceiling?

I need to apply the ceiling function to arbitrary sized (long) integers. However, division automatically returns the type of its operands, so that, for example: math.ceil(7/4) returns 1. I can use float, as in: math.ceil(7/float(4)), except that for very large integers float causes an unacceptabl

Green's Function

Hi All, I am new to Python and trying to solve the Hamiltonian of a linear chair of atoms using green’s function. Does anyone know any pre-existing library functions and literature that could be helpful? Thanks EOF - Looking for last minute shopp
