[PD] how to get big numbers from array into a file?

"double precision" has nothing to do with the data bus width. It just 
means that "t_float" and "t_sample" are defined as "double" instead of 
"float".

So "single precision"/"double precision" and "32-bit"/"64-bit" are 
really orthogonal. In fact, you can build a "32-bit double precision Pd".

I think so (prove me wrong!), because it foremost depends on the 
implementation of "%g" for "sprintf".
