*My* calculator does it right. Pressing the same sequence of keys gives this result:

Your calculator throws an error because it doesn't know how to do it. I
didn't need a calculator for something so simple.
My wife's calculator also does it right, with the result -E-, same as it gives for the square root
of a negative number, logarithm of a nonpositive number, inverse sine of 2, etc.
I know how to find the square root of a nonpositive number (actually,
both of them). Every number had TWO square roots. A little hint: when is
360 equal to 0?
BTW, every number has three cube roots too, but that may be a bit more
complicated.
