This part of the test does not do anything now because these two values are not in the `precisions` array and the `if` below always fails.

This loop seems completely pointless to me. It was pointless before and is even more pointless now. Simply remove the `$.each` loop and the `if` and replace the remaining `precision` with `testPrecision`. The number of assertions made should increase from 1 to 4 then.

Looks like the test should be refactored even more, but not in this patch. :-)
