Feature request: Output in engineering notation

[tdellspe]

It would be great value to select the engineering notation for the output.

a = 2*10^5   >>> write as 200*10^3 in output window
a = 2*10^-5  >>> write as 20*10^-6 in output window

In MATLAB, the corresponding command would be format shortEng.

Such an option could either be implemented in the GUI of CalcPad (e.g. a tick box in the status bar) or in the code itself by an output control command (e.g. #engnotation or similar).
