Still have a few logistical issues to iron-down and these fliers will be ready for prime-time. Hopefully, they’ll be ready to go out this time next week.

]]>We will need to start by reviewing the concept of modulus division. Let’s look at the standard division problem 5/2. We would typically say that the answer is 2.5 and this would be correct.

Now, modulus is simply the remainder of a division problem. Go back to when you were first introduced to division. In Texas, this is typically in 4th grade. Let’s take a look at that division problem of 5/2 again. When you were learning division, you would have said the answer was 2r1. The 1 is the modulus. When we’re writing the problem to just solve modulus, we would write it as 5%2.

Let’s say that we have the decimal number (base 10) 4,814 and we want to convert it to an octal (base 8).

We will be building the number from right-to-left. The first thing we will do is solve 4,814/8. This equals 601r6. So, our first digit of the solution (starting on the right) is 6.

6

Now, we solve 601/8, which equals 75r1. So, our second digit of the solution (floating from right-to-left) is 1.

16

Now, we solve 75/8, which equals 9r3. So, our third digit of the solution (floating from right-to-left) is 3.

316

Now, we solve 9/8, which equals 1r1. So, out fourth digit of the solution (floating from right-to-left) is 1.

1316

Finally, we solve 1/8, which equals 0r1. So, our fifth and final digit of the solution (floating from right-to-left) is 1.

11316

So, the decimal number (base 10) 4,814 is equal to the octal (base 8) 11316.

As you can see, this is a bit of a process, but once you know the process, it is very simple. I now want to take a look at going to number systems with more digits than base 10, for example: base 16.

Let’s say that we have the decimal number (base 10) 4,814 and we want to convert it to a HEX (base 16).

We start by solving 4,814/16, which gives us 300r14. Remember, that is number systems with more than 10 digits, we start using letters.

10 = A

11 = B

12 = C

13 = D

14 = E

15 = F

So, the first digit of our solution (building from right-to-left) is E.

E

Now, we solve 300/16, which gives us 18r12. So, the second digit of our solutions (building from right-to-left) is C.

CE

Now, we solve 18/16, which gives us 1r2. So, the third digit of our solution (building from right-to-left) is 2.

2CE

Finally, we solve 1/16, which gives us 0r1. So, the fourth digit of our solution (building from right-to-left) is 1.

12CE

So, the decimal number (base 10) 4,814 is equal to the hexadecimal (base 16) 12CE.
