Allow point (".") and comma (",") to be used in keyboard as separator and not only one

[MarioLunaSG]

🚀 feature request

Currently i can set the thousands separator as point or comma. If i set it to comma, the point button doesn't add a separator.

I suggest that the comma also should be allowed and replaced with the desired separator (.)
I set comma as separator, but point adds a comma and viceversa.

i have to use a separate directive to catch input and add this feature in order to achieve this but mobile is a bit trickyer to do when the directive itself could add this as an optional feature
Thanks!

Hi Mario, while this behavior is not native, I think the inputTrasnformFn (https://jsdaddy.github.io/ngx-mask/#1) may help you. It is easier than "use a separate directive".

Set the follow function in this property:

private swapCommaPeriodSeparator(rawValue: string): string {
  const defaultDecimalSeparator = ',';
  const [lastCharacter] = rawValue.split('').reverse();
  const isLastCharacterSeparator = ['.', ','].includes(lastCharacter);
  const isValidDecimalSeparator = lastCharacter === defaultDecimalSeparator;
  
  if (!isLastCharacterSeparator || isValidDecimalSeparator) {
	  return rawValue;
  }
  
  // Remove the last character and add the decimal separator
  const formattedValue = rawValue.slice(0, -1).concat(defaultDecimalSeparator);
  return formattedValue;
}
