outerWidth()/outerHeight() may return wrong results in IE with enabled hw rendering

Reported by: jquery@… Owned by: jquery@…

Component: dimensions Version: 1.8.0

Description

Because IE is using float for internal calculated widths ands heights using outerWidth()/outerHeight() does not always return the correct integer result.

Example:

<div><span>Text portion 1</span><span>Text portion 2</span></div>

$('div').width($('span:first').outerWidth() + $('span:last').outerWidth());

This should set the div to a width so that both span contents can be displayed in one line. But the internal calculated width of the spans can be something like '88.17' or '88.49'. jQuery will return '88' for each.

So the width of the div will be 176. The browser internally needs 176.66 pixels to render both spans. So the correct width will be 177. So the divs width has one pixel missing. The last character will not fit into the container.

Tested in IE 9.0.8112.16421 32 bit on Windows 7. Settings are default. Nothing changed. In firefox and chrome this works fine.

Thanks for the test case. So is the suggestion here for outerWidth/OuterHeight to return the float instead of an int if it can?

I think returning float would be the best for calculations, but it might break current implementations. However, for example using $.('div').width(176.66) must be interpreted correctly. I'm thinking about an internal Math.ceil when setting a value inside the width function and other functions that are dealing with widths and heights.

I've updated the fiddle: http://jsfiddle.net/y6Dmt/2/ I added two input fields, background and animation. In microsofts developer tools inputs have a calculated width and height which is correctly shown.
