Thread: Calculator Recommendation

Hi, I am looking for a non programmable calculator that can perform complex number calculations, specifically square root of complex numbers. I have a casio fx 991ES but it seems unable to square root complex numbers. Thanks

What is the maximum you are willing to spend on it?

Also, if the calculator is indeed programable, you need not use that functionality if you don't want to.
