> NumberFormat.js contains the following code:
> TrNumberFormat.prototype.percentageToString = function(number)
> {
>   number = number * 100;
>   number = this.getRounded(number);
> ..   number = this.numberToString(number);
> }
> consideration the number of fractionDigits but numberToString later will.
> TrNumberFormat.prototype.getRounded = function(val)
> {
>   val = this.moveDecimalRight(val);
>   val = Math.round(val);
>   val = this.moveDecimalLeft(val);
>   return val;
> }
> Math.round function will round to the nearest integer. With the earlier multiplication
to 100, precision is preserved to at most two digits, regardless of the maxFractionDigits
attribute.
