Data type
In signed binary data, the leftmost bit indicates the sign of binary 16-bit data. The value is expressed in
4-digit hexadecimal.
Positive Numbers: A value is positive or 0 if the leftmost bit is 0 (OFF). In 4-digit hexadecimal, this is
expressed as 0000 to 7FFF hex.
Negative Numbers: A value is negative if the leftmost bit is 1 (ON). In 4-digit hexadecimal, this is
expressed as 8000 to FFFF hex. The absolute of the negative value (decimal) is expressed as a two’s
complement.
Example: To treat –19 in decimal as signed binary, 0013 hex (the absolute value of 19) is subtracted
from FFFF hex and then 0001 hex is added to yield FFED hex.
