How do I force the display of a decimal in an ExtJS NumberField to a certain precision?

Question

I have a form with a NumberField that gets values of type float from JSON. If the values happen to be whole numbers, then no decimal places are sho

if you want something like below:

enter 50 > u got 50

50.10 > 50.10

50.123 > 50.12

Try this:

, setValue: function (v) {
      if ( !v || isNaN(v)) {
        v = '';
      }
      else if (v % 1 != 0) {    //means number is not whole number
        v = this.fixPrecision(String(v).replace(".", this.decimalSeparator));
      }

     return Ext.form.NumberField.superclass.setValue.call(this, v);
}
, fixPrecision: function (value) {
    if (!this.allowDecimals || this.decimalPrecision == -1) {
       return value;
    }

    return parseFloat(value).toFixed(this.decimalPrecision);
}
