This has nothing to do with OS X. Seems like Maxima cannot numerically evaluate `gamma_greek`. You can work around it by using `gamma_incomplete`, which Maxima does know how to evaluate numerically. If I'm not mistaken, `gamma_greek(10,1) = gamma_incomplete(10,0) - gamma_incomplete(10,1)`. --- ** [bugs:#3277] gamma-related functions under OS X** **Status:** open **Group:** None **Created:** Thu Jan 19, 2017 12:50 AM UTC by kofoid **Last Updated:** Thu Jan 19, 2017 12:50 AM UTC **Owner:** nobody I am running maxima 5.38.0 under OS X 10.10.5.

Um, David, please bear in mind that OP very probably can't tell if the problem depends on the operating system or not. So I will suggest to you to try to understand what you write from someone else's point of view to determine whether your tone is appropriate for this medium. --- ** [bugs:#3277] gamma-related functions under OS X** **Status:** open **Group:** None **Created:** Thu Jan 19, 2017 12:50 AM UTC by kofoid **Last Updated:** Sun Jan 22, 2017 02:36 PM UTC **Owner:** nobody I am running maxima 5.38.0 under OS X 10.10.5.

Robert, I honestly don't see how my comment could be called "inappropriate in tone". Maybe it's because I'm not a native speaker of English. It certainly wasn't meant negative in any way, I even spent some time reproducing it and finding a workaround. Apologies if it came off the wrong way. --- ** [bugs:#3277] gamma-related functions under OS X** **Status:** open **Group:** None **Created:** Thu Jan 19, 2017 12:50 AM UTC by kofoid **Last Updated:** Sun Jan 22, 2017 02:36 PM UTC **Owner:** nobody I am running maxima 5.38.0 under OS X 10.10.5.

"This has nothing to do with ..." sounds strongly dismissive in English. "This appears to happen on other platforms too" or "It doesn't appear to be related to the operating system" or "I have determined the problem is due to ..." are more neutral. I'm rather sensitive to tone, because, in this text-only universe we inhabit, all we have are words to communicate.

OP, there are at least 4 ways to compute numerical values for `gamma_greek`. ~~~~ (%i1) gamma_greek(10, 1), numer; (%o1) gamma_greek(10, 1) (%i2) gamma(10) - gamma_incomplete(10, 1), numer; (%o2) 0.04043407755671069 (%i3) gamma_incomplete(10, 0) - gamma_incomplete(10, 1), numer; (%o3) 0.04043407755671069 (%i4) gamma(10)*(1 - gamma_incomplete_regularized(10, 1)), numer; (%o4) 0.04043407756135764 (%i5) gamma_incomplete_generalized(10, 0, 1), numer; (%o5) 0.04043407755671069 ~~~~ It is a bug that `gamma_greek` doesn't have its own numerical evaluation. It can easily be resolved by punting to one of the methods above, although it's not clear to me which is most accurate. Aside from `gamma_greek`, did you find other gamma functions which do not evaluate numerically? I can't find any examples other than `gamma_greek`. --- ** [bugs:#3277] gamma-related functions under OS X** **Status:** open **Group:** None **Created:** Thu Jan 19, 2017 12:50 AM UTC by kofoid **Last Updated:** Sun Jan 22, 2017 02:36 PM UTC **Owner:** nobody I am running maxima 5.38.0 under OS X 10.10.5.
