Before calling pseries::power_const(), make sure the basis series has sufficient terms. In particular, do not shrink the order of expansion - only grow it. Fix various hairy problems in pseries::power_const() when a polynomial is raised to a positive integer power. (The special cases here can actually also be computed by Taylor expansion but the fixes should be more general.) Also add test cases.

When used interactively ginsh consumes the input line-by-line, so if a complete expression is entered it is enough to end the line to get an evaluated result. In the non-interative mode (i.e. if the input is not a tty) the input is consumed in blocks, making it impossible to use ginsh as a subprocess. This patch makes the non-interactive mode reuse the same line parsing logic as the interactive mode (without readline), but skips printing the "> " prompt, preserving the backward compatibility. ----------------------------------------------------------------------- Summary of changes: ginsh/ginsh_lexer.lpp | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

Compilation with MinGW on Windows
by Vladimir V. Kisil 12 Feb '23

12 Feb '23

Dear All, I am compiling GiNaC v1.8.6 on Windows using MinGW from Qt distribution pack. The compilation stopped with the error: factor.cpp:2397:75: error: ambiguous overload for 'operator=' (operand types are 'GiNaC::numeric' and 'long long unsigned int') 2397 | ctx.modulus = (ctx.vnlst.size() > 3) ? ctx.vnlst.size() : 3; | ^ I was able to finish the compilation by replacing the line with: ctx.modulus = (ctx.vnlst.size() > 3) ? ctx.vnlst.size() : numeric(3); Just in case I am attaching this as patch.

GiNaC 1.8.6 released
by Richard B. Kreckel 09 Feb '23

09 Feb '23

Hi, GiNaC 1.8.6 has been tagged and released. The News: * Fix wrong numeric info on transcendental functions. * Fix crash of evaluation of binomial(n, k) with negative integer n, k. Happy hacking! -richy. PS: If anyone knows how to push a commit together with the tags using git, do let me know. Yes, I've googled it up and tried several things but it never worked. -- Richard B. Kreckel <https://in.terlu.de/~kreckel/>
