[BangPypers] packing floating data

[Srinivas Reddy Thatiparthy]

Yes, you need to pack real and imaginary parts separately.I mean ,there is no way to pass Complex object to pack method(well,struct
performs conversions between Python values and C structs represented as
Python bytes objects),so

struct.pack('ff',realpart,imaginarypart) #provided both parts are floats.
