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.

How to calculate the affix of a 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.

How to calculate the affix of a vector?

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 $
