Is it possible to increase the accuracy of print_csrc_double output?

Not really. The accuracy is actually maximal. :-) What happens is that the precision for type double of your ostream object is set to 6 decimal digits, rather than 16 or 17. Just call `cout.precision(16)' before printing the expression.

print_csrc_double in GiNaC-1.0.8 shows only 6 decimal digits but I would like to have at least 16 digits displayed. Is it possible?

Well, I am considering to bump up the precision to 16 decimal digits for double output in `numeric::print()' before attaching the return value of `numeric::to_double()' to the stream in question (i.e. `c.s') and resetting it to the normal value afterwards. I don't think this would cause any side-effects, do you? Regards -richy. -- Richard B. Kreckel <Richard.Kreckel@GiNaC.DE> <http://www.ginac.de/~kreckel/>
