Types also provide a set of operations that can be performed on this encoding. So far we have used two types: int and double Integers Integers Integers can be converted from base 2 Negative integers are more complex 01000001 01000010 01000011 01100001 01100010 01100011 00110001 65 66 67 97 98 99 49 Negative Binary Numbers Negative Binary Numbers How do we encode negative numbers in binary? Consider our 4 bit overflow problem. This implies that 1111 in our 4 bit representation could stand for...
