... represented by its base ten equivalent . In turn , these byte representations are separated by periods . For example , 12.5 represents the pattern 0000110000000101 ( the byte 00001100 is represented by 12 , and 00000101 is represented ...
... represented . Thus , the leftmost bit is often called the sign bit . In a two's complement system , negative values are represented by the patterns whose sign bits are 1 ; nonnegative values are represented by patterns whose sign bits ...
... ( represented as 1011 ) and then perform the addition process of 0111 + 1011 to obtain 0010 , which represents 2 , as follows : 7 -5 0111 -0101 0111 +1011 0010 → 2 We see , then , that when two's complement notation is used to represent ...
