4325,CC() fails on Mathematica output,ddrake,was,"Using 3.1.2 on sage.math:
{{{
sage: mathematica.eval('N[BesselK[1+I, 2+ 3*I], 20]')
         -0.105203133241753451256 + 0.017589014615189905553 I
}}}
Now say I want to get a CC element out of that:
{{{
sage: CC(mathematica.eval('N[BesselK[1+I, 2+ 3*I], 20]'))
------------------------------------------------------------
   File ""<string>"", line 1
     -RealNumber('0.105203133241753451256')+RealNumber('0.017589014615189905553')I
                                                                                 ^
SyntaxError: unexpected EOF while parsing

}}}
It's confused because Mathematica uses a space between the number and I; a workaround is to put in an asterisk:
{{{
sage: CC(mathematica.eval('N[BesselK[1+I, 2+ 3*I], 20]').replace(' I', '*I'))
-0.105203133241753 + 0.0175890146151899*I
}}}
I understand that this kind of parsing can get difficult and complicated, but it seems like something we should aim for.",defect,closed,major,sage-duplicate/invalid/wontfix,interfaces,wontfix,mathematica,,,,,,,,
