Percentages were normally calculated but the unit have been changed to "px"

I wrote the following code:
var anim = morpheus([el, el2], {
left: 50+"%",
top: 50+"%"
});

Then I had run it in Chrome and inspected el and el2 with the developer tools, their left and top were all animated to "50px" instead of "50%";
