-System flag -103 formally sets the calculator mode to complex: ''​-103 SF''​.+System flag -103 formally sets the calculator mode to complex: ''​-103 SF''​. ​ This is important to ensure all input to functions return complex results. ​ For example, without setting flag -103, taking the square root of -1 results an an error (Argument outside domain). ​ Whereas in complex mode, the square root of -1 returns the correct result ''​(0,​1)''​.
