You can use any ECQL expression in your CSS filters.
[IEEERemainder(longitude, 10) = 0][IEEERemainder(latitude, 10) = 0] {

Keep in mind that even slightly complicated filters can defeat the
simplification algorithm in the CSS compiler and make the SLD output very
large - so generally you should avoid using functions in the selector when
your style has many rules.
Martin recently added a nice reference for ECQL syntax to the manual:
http://docs.geoserver.org/latest/en/user/filter/ecql_reference.html
You can consult your WFS capabilities document to see what filter functions
are available to you.
