Hi Rafa,

Formatting of numbers is based on the ‘locale’ setting and the numberFormat property. Smart.NumberInput uses https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/NumberFormat and this makes it unnecessary to have properties like decimalSeparator as it is applied automatically.
