Any support for 64 bit numbers?

Hi @japaric, from looking through the code it appears there aren't any 64 bit representations. Is that true, or am I reading it wrong? There's a lot of macro magic going on so maybe I'm missing it.

I'm looking for a fixed point implementation for a game physics engine I'm working on, and of the several options fpa appears to be the only one with any built-in trig support.
