Conversion from decimal number to hexadecimal:
We use two steps. First convert the decimal number to binary number of 4 or 8 or 16
bits, depending up on whether the decimal number is less or equal to 15 (= 2
4
1), 255 (= 2
8
1) or 65535 (= 2
16
1). Conversion is done as in Example 2.2. Now the binary number can
be converted to hexadecimal easily by using each nibble for converting to a hex digit, as

Let decimal number be 56
d
. This is more than 15 and less than 255. Hence 8-bit binary
number or two hex-digit ...
