* summary: [with patch, needs more doctests] New module complex_mpc
using lib mpc for complex multiprecision
arithmetic => [with patches, needs review] New
module complex_mpc using lib mpc for complex
multiprecision arithmetic
Comment:
I added a patch trac4446_doctests.patch, which does a number of things:
* adds doctests for all functions except three internal use only
functions
* changes _repr_ of complex numbers so that it agrees with the way
complex numbers are currently printed in Sage
* makes MPComplexField inherit from ParentWithGens, being generated over
its real field by the square root of -1 (just as it is now); this required
adding a few functions. So now one can do
{{{
sage: from sage.rings.complex_mpc import MPComplexField
sage: MPC.<j> = MPComplexField()
sage: j^2
-1.00000000000000 + 0.000000000000000*I
}}}
Note that only the last three patches should be applied, in order:
complex_mpc.p0.patch, trac4446_fix.patch, and trac4446_doctests.patch
