浮点数显示错误

Question

I am using Autodesk Infraworks software and have to set some tips using both javascript and html.

I use a set of table where there is a field called USER_SUM_ALL. It stores different numbers like 10, 20, 20.3, 20.8 etc.

The problem is that that program shows number not like in original but with 15 digits after comma. This is a code:

<div><b><font size="5"> TEST: %USER_SUM_ALL% </font></b></div>

And it shows not 20.8 but 20.800000000000001

What can be done here to display numbers properly?

Upd.

<script>
function test(){
    var x = %USER_SUM_ALL%;
    document.write(x);
};

</script>


<div><b><font size="5"> Number is: <script> test() </script> </font></b></div>

Here my goal is to show the number in field USER_SUM_ALL . Right now it doesn't react to field outside HTML tags.

Answer 1

使用javascript，您可以选择点号（。）示例后的数字大小。number.toFixed（2）返回点号后的2个数字。
