这个网上找的一个计算器插件，自己在里面做了些许修改，适应了现在所使用的情况，但是现在涉及到小数点计算，求教大神，如何修改能让其支持小数点计算，代码如下，多谢
var template =
'<span class="jcalculator">' +
'<span>7</span>' +
'<span>8</span>' +
'<span>9</span>' +
'<span class="plus operation">+</span>' +
'<span>4</span>' +
'<span>5</span>' +
'<span>6</span>' +
'<span class="minus operation">-</span>' +
'<span>1</span>' +
'<span>2</span>' +
'<span>3</span>' +
'<span class="multiplication operation">x</span>' +
'<span class="clear operation">C</span>' +
'<span>0</span>' +
'<span class="equal operation">=</span>' +
'<span class="divide operation">÷</span>' +
'</span>';

});
return controller;

})(jQuery);

.jcalculator span:active {
line-height: 27px;
}
.jcalculator .operation {
background: #191919;
}
.jcalculator .operation.equal {

}
调用要jquery依赖
$('#test').calculator();
<span class="demonstration">
<input id="test"/>
</span>
