function format(arg){
            var tmp,result = '';
            if(typeof arg !== 'undefined' && typeof parseFloat(arg) === 'number' && parseFloat(arg).toString() !== 'NaN'){
                if(parseFloat(arg) >= 24)
                    return "24.00";
                arg = parseInt(arg*100) / 100;
                tmp = arg.toString().split('.');
                if(tmp.length === 1){
                    if(tmp[0].length === 1){
                        tmp[0] = "0" + tmp[0];
                    }
                    return tmp[0] + '.00';

var v_0;
var v_1;

var arr=v.split(".");

if(arr[0].length==1)v_0="0"+arr[0];
