    The problem seems to be caused by removing property 'translate from 'mcond (in boolsimp.lisp) and then compiling a routine with return inside a conditional.

  • Raymond Toy Raymond Toy posted a comment on ticket #4669

    The docstring says it should be an integer. And it also says -1 means all integers are expanded. So should it really accept any real number? I did notice that factlim:3.0 works (with HEAD), but then double_factorial(6) returns 48.00000...1. But with the default factlim value of 100000, double_factorial returns 48. Not sure what's going with that, but that's probably a different issue from this one. Easy enough to add a :setting-predicate for factlim to make sure it's a real (or integer) so that it...

    non numeric value for factlim

  • Barton Willis Barton Willis posted a comment on ticket #4668

    User documentation: Function: genfact (x, y, z) Returns the generalized factorial, defined as x (x-z) (x - 2 z) ... (x - (y - 1) z). Thus, when x is an integer, genfact (x, x, 1) = x! and genfact (x, x/2, 2) = x!!. From the source code, it's clear the intent is for the second argument to be rounded down to the next integer (floor)--otherwise we'd have a product from 0 thru a half integer for the !! case. I'll look at double_factorial.

    Thank you for the bug report. I have confirmed that the bug exists in Maxima 5.47 and it appears to have been fixed before 5.48. Can you try again with a more recent version of Maxima, either 5.48 or, preferably, 5.49, the most recent version?

    Incorrect integration leads to incorrect series in fourie package

  • Robert Dodier Robert Dodier modified a comment on ticket #4660

    Dear Devin Greene, In case you are interested, our package pdefourier solves this problem and many other potential problems when the input contains trigonometric expressions or a product of a polynomial and a trigonometric expression https://github.com/emmanuelroque/pdefourier I hope you find it helpful. There is also an arxiv preprint where we explain why even Mathematica has many issues regarding Fourier series. https://arxiv.org/abs/2004.02604 Best, Emmanuel

    numeric evaluation of genfact

  • Robert Dodier Robert Dodier posted a comment on ticket #4668

    For the record, the source code for genfact in src/asum.lisp shows that it simplifies only for first and last arguments which are fixnums, and second argument such that floor yields a fixnum. Probably the documentation should mention that. I didn't find any description of what genfact is supposed to implement, exactly. I don't see any statements in the code and a web search for "generalized factorial" doesn't seem to find anything. I think maybe it would be good if we can say what it is that we believe...
