(50g) Bernoulli polynomials

[peacecalc]

Hello ijabbott,

thank you for answer!

In general I tried to write a program for the hp50g, that uses the formular from ttw and another which operates with three sums, but the results are strange...

The calc needs the complex mode and and for higher B_n(x) (n >= 11) I get wrong results (for n is odd B_n(0) = Bernoulli Number has to be zero, but it isn't), and more worse: the resulting coefficients are outputed as floating point numbers, even when the input are integers (and same in program)? And sometime the psi-function appears? I'm not shure, but is there a bug known for the summation command?
