After I create an svg image and save it as svg plain code, I notice a lot of numbers after the decimal point on all the shapes I create.

I am looking for a book, tutorial or suggestion on a setting within Inkscape that will round these numbers to make my code simpler.

Thanks for any help.

I think your only option is to open your SVG in an fully featured text editor and write a regular expression to strip the decimals.

But if the drawing looks the way you want, what do the decimals matter?

It's "numericprecision" attribute in preferences.xml. See: http://kaioa.com/node/25

tried that, but then Inkscape crashed badly - see this bug report.
(using 0.46+devel and 0.47pre, don't know if it works with 0.46)

use a grid and snap to that while drawing.
that works for me.
