The affix of a complex number $ z $ is the name given to the form $ a + ib $ of the complex number, with $ a $ the real part (coordinate $ x $) and $ b $ the imaginary part (coordinate $ y $) in the complex plan.

The term **affix** is less and less used today because it is generally replaced by the general term *complex number*.

The affix calculation can be performed from the position of the number in the complex plane:

__Example:__ An point with abscissae $ 2 $ (x-axis, real part) and ordinate $ 3 $ (y-axis, imaginary part) in the complex plane has the affix $ z = 2 + 3 i $

The calculation can also come from a vector of the plane.

The affix of a vector is the complex number equivalent to it (same coordinates in the complex plane)

__Example:__ A vector of the complex plane with components $ (4,2) $ has the affix $ z = 4 + 2 i $
