These little shortcuts in add::split_ex_to_pair(ex) and in add::combine_ex_with_coeff_to_pair(ex, ex) avoid the creation of new ex objects. These pieces of code are executed so often that this patch speeds up GiNaC by 5-10%, depending on test. commit 345f0c93051c01cdb5ab879b57f70118978fa9d0 Author: Richard Kreckel <kreckel(a)ginac.de> Date: Fri Nov 6 15:04:49 2015 +0100 Fix little missed optimization. commit 69f9dc042d1d10fff1fc9cc9a5c64a6f8ebd10be Author: Richard Kreckel <kreckel(a)ginac.de> Date: Fri Nov 6 01:00:55 2015 +0100 Replace dynamic throw() with static noexcept operator. ----------------------------------------------------------------------- Summary of changes: ginac/add.cpp | 8 +++++-- ginac/ex.h | 74 ++++++++++++++++++++++++++++----------------------------- ginac/power.cpp | 2 +- ginac/ptr.h | 36 ++++++++++++++-------------- 4 files changed, 62 insertions(+), 58 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

evalf() on cube roots
by Jan Rheinländer 02 Aug '15

02 Aug '15

Hi, I noticed that evalf( (-1)^(1/3) ) gives 0.5+0.86602540378443864673*I Is there any way to tell GiNaC to return the real root by default? Jan
