Description:
This function calculates the square root of the argument.
If the input type is real, then it calculates just the square root of real numbers! This means, sqrt(-4) = not defined (result is unpredictable).
If the input type is complex, then it calculates the square root of complex numbers! This means, sqrt(-4) = 2i.
