Closing bug. 672511 6 ap 2012-07-18 10:41:43 -0700 This is fixing Platform code. Is that code used anywhere? An actual regression test would be vastly preferable to a unit test (which is not even cross-platform!) 673047 7 yosin 2012-07-18 18:17:17 -0700 (In reply to comment #6) > This is fixing Platform code. Is that code used anywhere? An actual regression test would be vastly preferable to a unit test (which is not even cross-platform!) The code is used in step-able input types, number, date, range, datetime, and so on. Although, it is hard to hit this case from HTML5/JavaScript, because the value is out of range of double. The purpose of fixing this is for test case (bug 91481) and that test case is supplement for LayoutTest. 152918 2012-07-17 22:22:34 -0700 2012-07-17 23:50:34 -0700 Patch 1
