[Maxima-discuss] significant difference?

[Peter v. S. <pet...@gm...>]

Hello,
I am checking a book from Miroslav Lutovac for the nomen q(k)=e^(-pi *
K'/K) of the elliptic functions.
He gives for k=sin(86degrees) a q of 0.2954883855586914 on page 512.
I did:
q(k):= (%e)^(-%pi * elliptic_kc(1-k^2)/elliptic_kc(k^2));
q(sin(%pi * 86/180)),numer;
And got: 0.2954883855586907
It is a very small difference - only in the last two digits, but is it
significant for something wrong?
Can anyone check this result?
with friendly greetings,
Peter
