## @defmethodx {@@infsupdec} decorationpart (@var{X}, @var{TYPE})
##
## Return the decoration of the decorated interval @var{X}.
##
## The returned value depends on the requested @var{TYPE}.
## @table @asis
## @item @option{char} (default)
## The decoration is a cell array of character strings and its size equals the
## size of its interval part. Possible values: @option{ill}, @option{trv},
## @option{def}, @option{dac}, @option{com}.
## @item @option{uint8}
## The decoration is a matrix of uint8 numbers and its size equals the size of
## its interval part. Possible values: @option{0}, @option{4}, @option{8},
## @option{12}, @option{16} as defined by IEEE Std 1788-2015, 14.4 Interchange
## representations and encodings.
