Complex Numbers in symengine

[muralidhar-nalabothula]

Is there a way to convert symengine I to 1j directly so that it's complex values can be used in regular python? The way I'm doing right now is convert to sympy object and then using the built-in complex function but this is computationally expensive. And also how to find real and imaginary parts?

@ronald00773 did you figure it out? Was your question about how to convert SymEngine's complex type to a Python complex type efficiently? I am going to reopen this until we have a good answer here.

@certik. Hi, @isuruf game me a very good answer on stackoverflow. Suppose x is a symengine complex or complex double then

x (in python complex) = (x.real_part()) + float(x.imaginary_part())*1j

This significantly improved the speed.

Sorry for not updating here.Btw there isn't a direct way

@ronald00773, Isuru just implemented a direct way in #265.
