# Thread: Forgot how to use binary code

1. ## Forgot how to use binary code

Can't believe I forgot, can someone refresh my memory, or send me a link. I'm bored at work and taking a geek test http://www.innergeek.us/ and I can't justify one of my answers unless I know binary code. Doing well on the test so far though..

2. ..Think base 2 instead of base 10..i.e. 8,4,2,1......2 raised to the third power = 8, 2 raised to the second power = 4, 2 raised to the first power = 2, two raised to the zero power = 1..
So.......0001=1
0010=2
0011=3
0100=4
1000=8
1010=10

...etc. and so on.......Good luck with your test

4. you actually know binary? good lawd, i use a decoder

5. shit it takes a good old computer programmer back in the 70-80's to know binary....all the good old classic..cobol, c, c+, basic, fortran...

....We use binary coding quite a bit to define machine tool parameters and analyze diagnostic information....

Actually, hexadecimal notation has always been used quite a bit more than binary. If you are an old school programmer you should know this!

But you must admit that hexadecimal notation is:

a) more useful and efficient than binary
b) more widely used in all aspects of programming and scripting
c) much cooler looking than a bunch of 0's and 1's

It's like f vs. 1111! Come on! What's not to like about that?
