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".
