(1) A CONTAINER is a 32-bit block of data that contains the data type used by a value. If signed, the value is sign extended. Padding is used in
the CONTAINER to ensure that it is always 32-bits.
(2) This value is used in the formulas used to convert the value between display units and internal units. See Formulas for Converting
on
page 114.
