How to Set 'percent' DataType in colModel ??

[Eddy-Q]

I find a demo in ParamQuery official website:
col.format = function (val) {
return (val == null || val == "") ? "" : (pq.formatNumber(val, "##.00%") / 100 );
};
col.deFormat = function (val) {
return (pq.deFormatNumber(val.split('%'), "##.00")* 100)
};
col.dataType = 'float';
I tried this one that I don't understand why DeFormat doesn't work.

I want to know how to calculate Numbers that are already "format"
Like.....................
100 * 11 * 0.3/ (1+0.3) =253.85
When I set format: ".00% "and type 30, it says" 30%, "but the value is actually 30 instead of 0.3.

---

我试过这个官网的，我不明白为什么deFormat 不起作用，
我想知道如何计算已经“格式化”的数字
比如…………
100110.3/（1+0.3）=253.85
当我设置格式：“.00%”和类型30时，它表示“30%”，但实际值是30而不是0.3。

% format is not supported yet, it would be supported in upcoming versions.
