CSS 小数 处理

在不同浏览器或者同一浏览器的不同版本中，CSS 都会对小数进行取整（直接去除小数还是会根据小数的大小进行判断就不一定了） 测试代码：

    
    
    
    
        .class1 {
            width: 10.1px;
            height: 10.8px;
            border: 0px;
            background-color: Black;
        }
    
    
        window.onload = function () {
            var div1 = document.getElementById("div1");
            var clientWidth = div1.clientWidth;
            var offsetWidth = div1.offsetWidth;
            var scrollWidth = div1.scrollWidth;
            var ul = document.createElement('ul');
            var oLi1 = document.createElement('li');
            oLi1.innerHTML = "div.clientWidth=" + clientWidth;
            ul.appendChild(oLi1);
            var oLi2 = document.createElement('li');
            oLi2.innerHTML = "div.offsetWidth=" + offsetWidth;
            ul.appendChild(oLi2);
            var oLi3 = document.createElement('li');
            oLi3.innerHTML = "div.scrollWidth=" + scrollWidth;
            ul.appendChild(oLi3);


            var clientHeight = div1.clientHeight;
            var offsetHeight = div1.offsetHeight;
            var scrollHeight = div1.scrollHeight;
            var oLi4 = document.createElement('li');
            oLi4.innerHTML = "div.clientHeight=" + clientHeight;
            ul.appendChild(oLi4);
            var oLi5 = document.createElement('li');
            oLi5.innerHTML = "div.offsetHeight=" + offsetHeight;
            ul.appendChild(oLi5);
            var oLi6 = document.createElement('li');
            oLi6.innerHTML = "div.scrollHeight=" + scrollHeight;
            ul.appendChild(oLi6);
            div1.appendChild(ul);            
        }
