Integer Representation

Signed and Unsigned Numbers

• unsigned numbers are positive and can represent larger numbers than their signed counterparts because they don’t have the bit capacity to carry the negative numbers within their mapping

• For non-negative numbers they share the same bit encoding patterns which makes it easy for conversion
  • when the negative numbers are mapped, their bit pattern goes from $big_{n} \,to -1$
