[Christian Bauer]

Update of /home/cvs/GiNaC/ginac

Modified Files:
	numeric.cpp print.h 
Log Message:
- complex numbers are printed correctly (using the STL complex<> template or
  cln::complex())
- in the CLN output, rational numbers use cl_RA()
- small integers are printed in a more compact format (e.g. "2.0" instead of
  "2.0000000e+00").
