As the following console session shows, we format long floats to six digits. This should be checked against other browsers, unified, and spec'd. > document.foobar = 1/9; 0.1111111111111111 > document.foobar 0.1111111111111111 > var x = document.getElementById('header') undefined > x <div id=​"header">​ > x.style.opacity = 1/9; 0.1111111111111111 > x.style.opacity 0.111111 154440 1 evan 2009-10-13 14:46:05 -0700 Another related question is what the upper bound on CSS values are. E.g., can I set foobar.style.left = 100000000000000000000000px? 173731 2 45276 evan 2009-12-20 07:18:38 -0800 Created attachment 45276 Page for testing float handling 173733 3 evan 2009-12-20 07:21:02 -0800 +simon, in case he's curious The attachment tries to summarize some corner cases that browsers might have. Next I need to run this on various browsers and see if there's any pattern they might agree on. (I only have a Linux box at the moment, but when I'm back at work I can test IE, Safari, and Opera.) 173966 4 simon.fraser 2009-12-21 07:47:10 -0800 I can take this to the CSS Working group. 178279 5 evan 2010-01-07 11:24:37 -0800 By the way, I realized that this attachment is probably confusing things a bit because we might be doing a float -> string conversion to print out the result in the table. That's probably using another printf()-like call that will introduce exponential notation etc. that may not be part of the code this is intending to test. 1895876 6 ahmad.saleem792 2022-09-02 14:58:36 -0700 I notice that there are changes in the Safari Technology Preview 152 and other browsers (Chrome Canary 107 and Firefox Nightly 107) despite Webkit adopting CSS Parser. All browsers differ from each other in few cases. Just wanted to highlight.
