The expressions in brackets are only executed at double-word data types.
In the case of signed byte and half word data types, a trap to Range Error occurs when the
value of the operand to be stored exceeds the value range of the specified data type; the
byte or half word is stored regardless of a Range Error.
Data Type xx is with:
BU: byte unsigned;
BS: byte signed;
HU: half word unsigned;
HS: half word signed;
W: word;
D: double-word;
