-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)''.

 The following table summarizes commands applicable to complex numbers, $z=x+iy=re^{i\theta}$. The following table summarizes commands applicable to complex numbers, $z=x+iy=re^{i\theta}$.
  
-| Command | Purpose | Example |+| Command | Purpose | Example ($\theta$ in degrees) |
 | ''C→R'' | Break down complex number to two reals | ''(5,3) C→R'' yields ''(5,3)'' ''5'' ''3''| | ''C→R'' | Break down complex number to two reals | ''(5,3) C→R'' yields ''(5,3)'' ''5'' ''3''|
 | ''R→C'' | Combine two numbers to a complex | ''5 3 R→C'' yields ''(5,3)''| | ''R→C'' | Combine two numbers to a complex | ''5 3 R→C'' yields ''(5,3)''|
