animate fails in IE with very small floating point values

Description

If you call animate with a very small floating point value (for example, 4.8e-14), IE will throw a script error "Invalid argument"

I am setting the animate value that small because I am animating objects radially, so I am calculating top/left using sin/cos, and thus for some angles, x or y ends up extremely small. This does not occur in any other browser (tested in Firefox 3.5, Safari 4, Chrome and Opera 10. All in Windows and OSX)

Please see attached example. It's a very tiny repro.

This is occurring for me in IE8 8.07100.0 on Windows7. It occurs in all rendering modes (Standards, Quirks, etc).

Workaround is trivial. If I find the value is very small, I just set it to zero before calling animate.

So I created a patch for this issue but I am just not sure it is worth fixing in core; it’s not an insignificant amount of code for an *extreme* edge case.
