docs: Set minimum number of decimals to use for formatting. If the value precision exceeds all decimals specified
  (including additional decimals specified by {@link #optionalDecimals(int...)} or
  {@link #repeatOptionalDecimals(int, int)}), the value will be rounded. This configuration is not relevant for
  parsing.
