Floored the slide width calculation

I was setting up a slider like so
<code>
$slider.bxSlider({
            minSlides: 1,
            maxSlides: 5,
            slideWidth: 174,
            slideMargin: 17,
            moveSlides: 3,
            pager: false,
            infiniteLoop: false,
            hideControlOnEnd:true
		});
</code>
and was getting widths like 174.4px

which is no good, this just floors that calculation.

I haven't minimized the js.
