What I am about to say may sound off-topic since it's an image of a calculator, but rest assured, it is on topic, since calculators are computers.
As you may have noticed in the image above, the complex number representation is not selected. Normally, for all of the settings, a mode has to be selected, so normally, you can't have no mode selected for any of this settings. You're probably wondering, how are complex numbers represented if no complex number representation is selected. Well, with the current settings, if you try to take the square root of a negative number, you get a domain error, so the mode that's actually set for the complex number representation is Real, meaning that all outputs are real numbers.
