                    010        101        001       111

                 Binary equivalent is (010 101 001 111) 2
                 After removing leading 0s in the integer part
                 (10101001111) 2

                 Example 2: Convert (621.04)  to binary.
                                          8
                 Answer:
                    6      2      1       .      0      4
                   110    010    001      .     000    100

                 Binary equivalent is (110 010 001.000 100) 2
                 After removing trailing 0s in fractional part
                 (110010001.0001) 2



                 1.2.10 Hexadecimal to Binary
                 The steps to be followed are:
                 1.  Convert each hexadecimal digit to its binary equivalent with the help of the table given previously that shows
                   relationship among different number systems.
                 2.  Arrange the newly converted binary digits together.
                 3.  Remove leading 0s in the integer part and trailing 0s in the fractional part to get the final binary equivalent.

                 Example 1: Convert (25C9)  to binary.
