Comment:
With #4330 being fixed I'm closing this ticket as fixed. The suggestion
given above ([comment:3 was]) works now with 3.4.1.rc4:
{{{
sage: a = mathematica('N[BesselK[1+I, 2+ 3*I], 30]')
sage: CC((a.Re(), a.Im()))
-0.105203133241753 + 0.0175890146151899*I
}}}
You lose a bit of precision, there, so you can use RealField and so on:
{{{
sage: a.Re()
-0.10520313324175345125609254499068
sage: RealField(100)(a.Re())
-0.10520313324175345125609254499
sage: RealField(110)(a.Re())
-0.10520313324175345125609254499070
}}}
Since this works now, and my original usage of {{{mathematica.eval}}}
isn't supposed to work, I say this is fixed.
