Jquery font size animation problem in Chrome, too laggy

I developed a little script that make texts 开发者_开发百科like they were coming from far, with Jquery and animate() function. Everything works well in IE and FireFox but on Chrome is very laggy, like it was loosing frames.

You cand test and play with the code here: http://jsbin.com/ehahoc/7/

I check the source and i something that mite couse the problem... Form firefox the font size and the opacity values are

0.0000 (4 digits)

and in chrome...

0.000000000000 (12-14 digits)

and the increased like :

0.000000000011

0.000000000124

Don't know if this helps or if this makes it buggy.
