numbers . Additional problems
Completion of thes e additional problems is not re quire d for la b2 cre dit. However, problems s imilar to thes e may s how up in a
future ex am. Bitwise logic
In this c alc ulator's language, a “&” is a bitwis e logic al AND, a “|” is a bitwis e logic al OR, a “^” is a bitwis e logic al XOR, and a “~ ” is a
bitwis e logic al NOT. In the abs enc e of parenthes is , bit s hifting is alway s done before AND whic h in turn is alway s done before OR,
in the s ame way that multiplic ation is alway s done before addition.
In 16-bit uns igned mode, run the following c omputations :
12. x 01fa & 1
x 3030 & 1
x 2911 & 1
x 01fa > > 4 & 1
x 3040 > > 4 & 1
x 2911 > > 4 & 1
x 0001 | x 0080 | x 0040
(x 0001 | x 0080 | x 0040) & x 0080
