When using FloatField as an admin list_filter, float values that cannot be represented with complete fidelity (such as 0.1) are displayed as filter options, but no models appear on the filtered list page.

list_filter should not compare equivalence with floating point numbers, it should test for membership in a range (v-ε, v+ε) for very small ε.

changed this to newforms-admin branch, that's where admin is living now.

The correct solution for this would probably be to create a FilterSpec to split the values into equidistant intervals and filter using those borders.
