Comment(by kcrisman):
I wasn't suggesting which of the several packages in Sage should be used
for numerical evaluation, though mpmath did come to mind :-)
I don't think that beta(0.5,0.5) would work, given that
{{{
sage: gamma(0.5)
1.77245385090552
sage: gamma(1/2)
sqrt(pi)
}}}
but beta(1/2,1/2) becoming pi should work fine once we have a symbolic
wrapper (with or without Ginac):
{{{
sage: maxima_console()
Maxima 5.21.1 http://maxima.sourceforge.net
using Lisp ECL 10.4.1
Distributed under the GNU Public License. See the file COPYING.
Dedicated to the memory of William Schelter.
The function bug_report() provides bug reporting information.
(%i1) beta(1/2,1/2);
(%o1) %pi
}}}
Please do try to add this! We definitely often get email asking for
various special functions both symbolically and numerically. Also, the
more examples we have, the easier it is to finish off the rest of them by
cut and paste.
