[GiNaC-devel] patch: valid C code for idx class with print_csrc

[Markus Grabner]

	Hi!

    Printing an indexed expression using an instance of the print_csrc_double 
class produces invalid C code (the same syntax that is used in the tutorial 
http://www.ginac.de/tutorial/Indexed-objects.html#Indexed-objects) in 
ginac-1.3.7. I understand that the index class in ginac is more powerful than 
the indexing facilities of the C language, but still I expected 
print_csrc_double to produce valid C code simply due to its name. So I added 
a few lines which handle the case of integer indices (numeric or symbolic) 
stored in the idx class (patch attached).

	Kind regards,
		Markus
