Octal - Binary

Octal    -    Binary  

Each octal digit can be represented by three binary digits as shown by the table below.

         

Octal	Binary
0	000
1	001
2	010
3	011
4	100
5	101
6	110
7	111

                                            

Ø   To convent octal to binary, each octal digit should be replaced by a 3 bit binary equivalent.

Ø   To convent binary to octal, group of three bits should be formed starting form the decimal point in both directions and replace each by the equivalent octal digit

Example 01:

                      256.48₈ – Binary

                         2         5         6        4       7

                         010    101     110    100    111

                     256.47₈ = 01010110.100111₂

Example 02:

                      11010011011.11001₂

                   

011          010       011       011.      110     010
