This returns the principal (positive) square root of the specified value. To find the other square root of a number, negate the value this returns. This is the inverse function of squaring For this function to return the square root of negative numbers, the mode must be either a+bi or re^θi. It will not work if the parameter is negative and the mode is Real.
