对金钱进行处理

function formatqfw(num) {
num = parseFloat(num);
var arr = [num.toFixed(0), ''];
if (num > 100000000) {
arr[1] = '亿';
arr[0] = (num / 100000000).toFixed(2);
} else if (num > 10000) {
arr[1] = '万';
arr[0] = (num / 10000).toFixed(2);
}
arr[0] = (arr[0] + '').replace(/\d{1,3}(?=(\d{3})+(\.\d*)?$)/g, '$&,');
return arr;
