Seems like it might be time to fix this weirdness: http://www.w3.org/TR/cssom-view/#extensions-to-the-mouseevent-interface

Change stuff from integers to floats, add the missing members, and define the members better.

Awesome. Thanks for the head's up.

Comment 2 Arthur Barstow 2015-03-21 15:11:51 UTC

Bulk move of all D3E bugs to the UI Events component.

Do we really want to make them floats when everyone is returning integers? (No objection, just curious)

They're double in Chromium

https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/core/events/mouse_event.idl;l=26

long in Gecko and WebKit

Interesting, Blink somehow still only sends integer values at least on my Surface screen (on Windows).

Edit: Ah it does send .5 values but only for pointer events. Cool. (Tested on https://patrickhlauke.github.io/touch/tests/event-listener-coordinates.html)

Yeah, indeed. These look like the relevant bugs for MouseEvent:

https://bugs.chromium.org/p/chromium/issues/detail?id=660057
https://bugs.chromium.org/p/chromium/issues/detail?id=456625

They're marked as Fixed. Was it changed back? cc @EiraGe
