And there are some strong arguments in favour of rectangular. Especially
the basic arithmetic operations are fairly straightforward in rectangular

polar representation).

Addition/subtraction is simpler using rectangular coordinates;
multiplication/division is simpler using polar coordinates.

However, multiplication/division is not horrible complicated
using rectangular coordinates, although the classical textbook
formula for complex division is subject to unnecessary
overflow (avoidable by normalizing against the larger
component of the divisor).
