WP 34S Displayformat

[smtschmidt]

My prefered notification is ALL 2 and ENGOVR. Up to 2 zeros can appear after the decimal mark before the display switches to engineering notation.

It works perfectly with irrationional numbers but i think it doesn't work with short rational numbers:
5 1/x > 0,2
10 / > 0,02
10 / > 0,002
10 / > 0,0002
and so on up to 10 zeros after the decimal mark.

Is this a bug or a feature?

Many thanks in advance,
Michael
