Comment (by jdemeyer):
Replying to [comment:12 kcrisman]:
> Also, is there/should there be a numerical approximation method for the
CC like you added for the RR? (This may be a dumb question.)
This is for `RealLiteral`, not `RealNumber`. Given that there is no
`ComplexLiteral`, no it doesn't have to be added. Remark also the
difference (with or without this ticket):
{{{
sage: a = RR(CC(1.3))
sage: b = RR(1.3)
sage: a == b
True
sage: RealField(200)(a)
1.3000000000000000444089209850062616169452667236328125000000
sage: RealField(200)(b)
1.3000000000000000000000000000000000000000000000000000000000
}}}
