Range of Data type

Range of Data type

Range of  any Data type = (A) ^{number of bit occupied by a data type}

Where, A = number of bits available in the language which is understand by computer i.e., 2

bits.

Range of byte

Range of byte =  (2) ⁸          =  2⁸/ 2   = 2⁷               // divided into two parts to get –ve and +ve range

                2⁷                   2⁷

- ve range   -2⁷  to  -1

+ve  range  +1  to  + 2⁷

                  -1                                   -1    

                0                                                    2⁷ - 1

Range of byte = 2⁷   to  2⁷ – 1

                         =  -128  to  +127
