8 weeks Burcin Erocal Added tag 0.1.11 for changeset f2cee4bc8528default tip
8 weeks Burcin Erocal Pynac 0.1.11.0.1.11
8 weeks Burcin Erocal Allow assigning custom python functions to special functions defined from c++.
8 weeks Richard Kreckel Add mul::info() and add::info() support for numeric info_flags.
6 months Golam Mortuza Hossain Expose TeX_name and domain of symbols to Sage
2 months Burcin Erocal Remove is_real() check from numeric::real(). The py_real() function provided
2 months Burcin Erocal Separate coefficients of rational functions into a numerator and denominator
2 months Burcin Erocal Fix serious printing issue, where coefficients of mul objects which printed with '-' as first character and contained -, + or a space were displayed wrong.
2 months Burcin Erocal [mq]: log_speedup.patch
2 months Burcin Erocal Make unarchiving functions with same name and different number of arguments work.
8 weeks Burcin Erocal Added tag 0.1.10 for changeset 334d96c6f328
3 months Burcin Erocal Pynac 0.1.10.0.1.10
3 months Burcin Erocal Minor fixes to auto* files to make them work with libtool-2.
3 months Burcin Erocal Make latex printing of nested powers work. Change mul and add to use \left and \right instead of ordinary parenthesis.
3 months Burcin Erocal Adjust exp simplification code in mul::eval to match the changes to exp_power in changeset 115:beb49aa3cebf.
3 months Burcin Erocal Use a customized FNV hash in fderivative::calchash().
3 months Burcin Erocal Change typesetting of functions to match Sage conventions.
3 months Burcin Erocal Prevent the automatic evaluation function of exp from raising errors. The
3 months Burcin Erocal Calls to custom evaluation, derivative, etc. methods now pass the function instance as first argument.
3 months Burcin Erocal Custom evalf methods take the Sage parent as argument instead of the precision.
5 months Burcin Erocal Put parenthesis around exp when printing powers.
5 months Burcin Erocal Pynac 0.1.9
5 months Burcin Erocal Make lgamma and tgamma stay symbolic for crational arguments.
5 months Burcin Erocal Make the special functions evaluate when given non-exact arguments again.
5 months Burcin Erocal Fix comparison of functions and fderivatives. #6524 on Sage trac
6 months Burcin Erocal Fix hash collision for derivatives of symbolic functions. #6851 on Sage trac
6 months Burcin Erocal Change latex printing of log to \log. #6902 on Sage trac
6 months Burcin Erocal Only simplify exp(a)^b -> exp(a*b) automatically if b is an integer. #6948 on
7 months Burcin Erocal Make the chain rule for derivatives of function optional.
7 months Burcin Erocal Add support for infinity to special functions defined in inifcns_trans.cpp.
7 months Burcin Erocal Make sure hash values for fderivative don't collide when only the paramsets
7 months Burcin Erocal Check for errors after call to py_print_fderivative().
7 months Burcin Erocal Print paranthesis around arguments of real_part() and imag_part() functions in
7 months Burcin Erocal Change the default TeX_name for functions to be {\rm name} instead of \mbox{name}.
9 months Burcin Erocal Several printing fixes:
9 months Burcin Erocal Conjugates of symbolic functions no longer just apply conjugate to the arguments.
9 months Burcin Erocal Fix serious bug in comparison of mul and pow objects. This used to cause arithmetic errors.
9 months Burcin Erocal Pynac 0.1.8.
9 months Burcin Erocal Add support for the simplification exp(a)*exp(b) -> exp(a+b) to mul::eval.
9 months Burcin Erocal Revert changes to symbol::calchash to avoid collisions. Since comparisons use
9 months Burcin Erocal Added tag 0.1.7 for changeset f49f41cda930
9 months Burcin Erocal Pynac 0.1.7.0.1.7
9 months Burcin Erocal Add error handling for py_get_constant.
10 months William Stein Fix problem taking real_parts: Problem R1 at http://wiki.sagemath.org/symbench
10 months Mike Hansen Re-enable polylog functionality.
10 months Robert Bradshaw Fix nonnegative, real/imag parts of log
10 months William Stein Add error handling to py_get_parent_char
10 months William Stein Fix bug with handling latex variable names.
10 months William Stein Fix bug with is_even.
10 months William Stein Remove hack from gethash that was added before and is not needed now.
10 months William Stein [mq]: gammaI.patch
10 months Mike Hansen Handle returning the eval and fderivative callbacks returning None.
10 months Mike Hansen Add the derivative of the absolute value function.
10 months Mike Hansen Have archiving of constants use Python.
10 months William Stein [mq]: pynac-stein-part2-better-diff.patch
10 months Robert Bradshaw Real crational, cinteger methods, powering tweaks for 2^I
10 months William Stein Printing fixes.
9 months Burcin Erocal Call rational_power_parts from Sage to simplify rational powers. E.g., sqrt(8)
10 months Mike Hansen Add a get_parameter_set method for fderivatives.
11 months Mike Hansen Make constants have a generic evalf function so that all of the constants get their numerical approximation via Sage.
