Takes the square root of a positive or negative number. It works exactly the same as 2×√ or ^(1/2) but is smaller and uses an ending parenthesis. If used on a list, it will return a list with the square root of each element.


        {1 i}

This may return a complex number or throw ERR:NONREAL ANS (depending on mode settings) if taking the square root of a negative number.
