I'm not quite sure what your problem is.  Is it that you need to compute 
and exponent of a complex number?  If so, you need to use mathematical 
identities to convert a complex expression into a real part and imaginary 
part, and then compute each part separately.  DJGPP C libraries don't 
support complex arguments at this time.

I don't know whether libstdcxx, the C++ library, does support comples 
math functions.  Anybody?
