* `thousands`: the thousands separator. default: ','
* `decimal`: the decimal separator. default: '.'
* `precision`: how many decimal places are allowed. default: 2
* `precision`: how many decimal places are allowed. use 'auto' for get the precision from the value or 'custom' for no limitations. default: 2
