Changes (by AlexGhitza):
* summary: complex arithmetic passes via pari => [with patch, needs
review] complex arithmetic passes via pari
Comment:
The attached patch does the following:
* based on Robert's example, gets rid of Pari calls in cos, cosh, sin,
sinh, tan, tanh, exp, sqrt, nth_root, !__pow!__
* adds csc() and sec()
* adds a !__nonzero!__() method to speed up is_zero()
* fixes doctests that were affected by these changes
The patch is currently based on 3.1.3.alpha1, and I'm putting it out as
such so that it can be reviewed. I am aware of some interaction with
patches that were merged in alpha2, so I will rebase it once alpha2 is
out.
