Description john Sheahan 2003-12-20 01:06:42 UTC 
Engineering notation is a scientific notation varient where the 
exponent is restricted to a multiple-of-3.

This used to be achievable in gnumeric (and excel)  using the custom cell
format
 ##0.0E+0
however that now produces the same output as conventional scientific notation.

for example, enter 0.01 into a cell
format->number->custom->##0.0E+0
preview is  +1.0E-02
but should be +10.0E-03

checked on recent gnumerics, including 1.2.2

Implementation of engineering notation

Here's a patch that fixes this issue, but non only.

It also adds an engineering notation check box in format dialog.

And it adds a new scientific format with superscript via pango markup, with its corresponding superscripted checkbox in format dialog. UI is disabled by default, but can be enabled with go_format_sel_new_full.
Use case for this format is nice axis labeling in graphs.

Implementation of engineering notation

Looks good, except for two details.

1. The check button for engineering notation needs a tooltip.

2. The glade file needs to be edited by hand and have the following killed.  (Alternatively, run glade with gtk+ 2.6)

(gnumeric:15327): libglade-WARNING **: unknown property `urgency_hint' for class `GtkWindow'

It doesn't look like this actually got committed.
