It sounds like what you want is arbitrary-precision arithmetic, which
is not what scipy is for (see instead packages like clnum or dmath).
NumPy is for calculating efficiently with large arrays of
floating-point numbers at machine precision, and scipy is a package of
scientific algorithms mostly taking advantage of numpy. While it is
possible to combine arbitrary-precision arithmetic with numpy,
arbitrary-precision arithmetic is exceedingly slow and unsuitable for
most numerical tasks.
