  //! Display the given argument as a decimal number. The dots between the digits (or colon)
  //! can be individually controlled.
  //!
  //! @param num The number to be shown
  //! @param dots Dot/Colon enable. The argument is a bitmask, with each bit corresponding to a dot
  //!        between the digits (or colon mark, as implemented by each module). i.e.
  //!        For displays with dots between each digit:
  //!        * 0.000 (0b10000000)128
  //!        * 00.00 (0b01000000) 64
  //!        * 000.0 (0b00100000) 32
  //!        * 0.0.0.0 (0b11100000) 224
  //!        For displays with just a colon:
  //!        * 00:00 (0b01000000) 64
  //!        For displays with dots and colons colon:
  //!        * 0.0:0.0 (0b11100000) 224
  //! @param leading_zero When true, leading zeros are displayed. Otherwise unnecessary digits are
  //!        blank. NOTE: leading zero is not supported with negative numbers.
  //! @param length The number of digits to set. The user must ensure that the number to be shown
  //!        fits to the number of digits requested (for example, if two digits are to be displayed,
  //!        the number must be between 0 to 99)
  //! @param pos The position of the most significant digit (0 - leftmost, 3 - rightmost)
  //void showNumberDecEx(int num, uint8_t dots = 0, bool leading_zero = false, uint8_t length = 4, uint8_t pos = 0);
