Editing Quater-imaginary base (section)

===Example===
If the quater-imaginary representation of the complex unit ''i'' has to be found, the formula without radix point will not suffice. Therefore, the above formula should be used. Hence:

:<math>
\begin{align}
i & = 32id_{5}+16d_{4}-8id_{3}-4d_{2}+2id_{1}+d_{0}+\frac{1}{2i}d_{-1}+\frac{1}{-4}d_{-2}+\frac{1}{-8i}d_{-3}\\
& = i(32d_{5}-8d_{3}+2d_{1}-\frac{1}{2}d_{-1}+\frac{1}{8}d_{-3})+16d_{4}-4d_{2}+d_{0}-\frac{1}{4}d_{-2}\\
\end{align}
</math>

for certain coefficients ''d<sub>k</sub>''. Then because the real part has to be zero: ''d''<sub>4</sub> = ''d''<sub>2</sub> = ''d''<sub>0</sub> = ''d''<sub>−2</sub> = 0. 
For the imaginary part, if ''d''<sub>5</sub> = ''d''<sub>3</sub> = ''d''<sub>−3</sub> = 0 and when ''d''<sub>1</sub> = 1 and ''d''<sub>−1</sub> = 2 the digit string can be found. Using the above coefficients in the digit string the result is:

:<math>i = 10.2_{2i}.</math>
