Table 4
Binary Numbers
Binary numbers are base-2 numbers. They are written as a
sequence of one's and zero's and end with a lower or upper case
"B". Table 3 shows how to convert any value between 0 and 15 into
its binary representation. To easily convert a number into its binary
number, first convert it to hexadecimal using Table 4. Then convert
the hexadecimal digit into its binary representation. Let's use the
value 90. Its hexadecimal representation is "5Ah". The binary
representation of "5" is "0101b", and the representation of "A" is
"1010b". All we need to do is lay the two numbers end to end. The
binary number representation of "5Ah" as "01011010b".
