I don't understand the question.  There is no way to express 1/2 LBS in an
integer.  To do that you need at least one fraction bit.  I assume you mean
how to convert an 8 bit integer to some representation so that the value is
1/2 original LSB higher?  If the original value uses all 8 bits, then the
new representation will require at least one more bit.
