                           CONVERSION OF DECIMAL TO BINARY


                 To convert a decimal number into a binary number, follow the given steps:
                 Step  1    Divide the decimal number by 2 while keeping track of the quotient and remainder.

                 Step  2    Continue dividing the quotient by 2 until you get a quotient of less than 2.
                 Step  3    Then write the remainder in the reverse order (from bottom to top) to obtain the binary

                          equivalent.
                 Example: Convert the (126)  to binary number.
                                             10
                                                            2  126
                                                            2   63     0

                                                            2   31      1
                                                            2   15      1

                                                            2    7      1
                                                            2    3      1
                                                                  1     1




                 The binary equivalent of 126 is 1111110 or (126)  = (1111110) 2
                                                                10

                           CONVERSION OF BINARY TO DECIMAL


                 To convert a binary number into a decimal number, follow the given steps:

                 Step  1    Multiply each digit of the binary number by 2 to the power of n, where n is the position of
                          the digit starting from 0 on the right.
