Decimal isn't the only way to represent a value - get acquainted with Binary & Hexadecimal, two very important numeral systems often found lurking within the depths of technology.

Over the years, I have enjoyed Collins videos. Collin has a hip coolness about him. He kicks butt! MORE.

Programmers also mix any of the notations when it's useful. For example, when assigning data to shift register, it's easy to see how binary is the most intuitive choice: "B10110011" vs. "179" to describe which LEDs are ON: ◦•◦◦••◦◦

Binary is also very useful when using port manipulation on arduino. www.arduino.cc/en/Reference/PortManipulation

+RealationGames On the other hand, when inputting a list of values, it's easier to say "0xE4 comes after 0xDA" rather than "B11100100 comes after B11011010"

An easy way to read binary numbers: Binary Number: 0 0 0 0 1 0 1 0 ----------------------------------------------------------------------------- Value of each number: 128 64 32 16 8 4 2 1 And the pattern continues to the left, doubling each number for each additional place. Then you add up all the numbers that contain a 1. So in this example it would be 2+8=10. Hope this helps. It made figuring out the value of binary numbers easy for me.

Collin, Please accept my apologies for my noob question. But, here goes: You showed us how counting to 5 or 6 worked in Decimal. Please explain how you find values in Hexadecimal. At the (3:34 Time Mark) I was under the impression that I should multiply the values of "F" & "C" to get a value of "252",considering that the "F" & "C" were side by side... However, I received a value of 180. Unfortunately, I need more than just the table of values. I also need how the value is calculated. Grateful appreciation (in advance) for your response, Collin.

@cosmosliger 9 жыл бұрын

I'm not Collin, but here goes: The way it works isn't actually multiplication- it's powers. In regular decimal, you have a 1's place, a 10's place, a 100's, 1000's and so on. They are powers of the base - in this case, base ten. Sooooo... in a base 16 (hexadecimal) number system, rather than having 1's, 10's, 100's, you have places that are powers of 16. This means you have a 1s place, a 16s place, a 256's place, a 4096's place, etc. Thus, just as decimal [2][5][2] has a value of [2]*100+[5]*10+[2]*1, the hex number [F][C] (which is really [15][12]) has the value [15]*16+[12]*1. This works out to 252. Thus, to work out a hex number such as 0x1A426C, which is [1][10][4][2][6][12], you would multiply the first (rightmost) digit by 16^0 (1), the next by 16^1 (16), the next by 16^2 (256), the next by 16^3 (4096), and so on, and then add it all up. Thus you get [12]*1 + [6]*16 + [2]*256 + [4]*4096..... = 1720940. Hope that made sense :)

@Desmaad 10 жыл бұрын

Some programming languages can use a wide variety of radices (bases) with various notation. My favourite is Python, where you you define a base with a prefix consisting of the base number and an r (Erlang is similar, but it uses a #, instead.)

Awesome explanation! Need more of these!! i had few doubts - 1) when you say 1, 0 are stored as electrical charges, is there any way to explain how exactly that happens? like say i declare a number like, int x = 10; how is it stored in the memory as charges & retrieved back again from charges? 2) how are memory addresses which are in hexadecimal understood by the machine in the context of 0 & 1 Thanks!

I remember octal was quite popular too a long time ago. Whatever happened to that? Was also very useful when making nerdy jokes, such as: Why do programmers celebrate Christmas on Halloween? Because 31 OCT = 25 DEC!

@rty1955 5 жыл бұрын

Octal was popular on Minicomputers like Digital Equipment Corp. (DEC) family if PDP conputers ir VAX's Some mini computers also used byte-octal so a 16bit number qould be reptlreaented like 177177.
