Complex numbers always seem to be displayed using cartesian coordinates.

When complex numbers represent rotations and displacements in 2-D
then rotations are better displayed in polar form
and displacements in cartesian.

1ad45    NB. rotate by 45 degrees

I wrote a simple polar format verb because i couldn't find an !:
option that would help.

Is there a global setting that controls the display format of complex?

Thanks
David
