Does anyone know how to add binary numbers and if you have any code that would be awesome. for example i need to add binarry numbers like so:
01000011.11011101.10100111.11000000
11111111.10000000.00000000.00000000
but i know a 1 and 1 cannot be 2 so is a 1 and 1 10 or 01, so as you can see im just making myself confused. Any help would be greatly apprecaited.
Regards,
Scott

It's just like decimal really except the numbers only go up to 1, so counting would be
decimal binary
0 0
1 1
2 10
3 11
4 100
5 101
6 110
7 111
8 1000
9 1001
10 1010
0 0
1 1
2 01
3 11
4 001
5 101
6 011
7 111
8 0001
9 1001
10 0101
I think Bigley got it backwards.

Hi, scottr.
There are two ways:
1- Make a function to convert your binaries into decimal, add the decimals together, re-convert to binary.
2- Use the very simple addition rule:
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0 plus a "carry"
That "carry" works just like in decimal, shift it one place to the left and add it to the digits that were in that place using the same rule.
HTH :)
P.S. Boothman_7: It seems your hand is shaking a bit (on the SubmitNow key, hahaha)
but Bigley is right: 10 = 1010; your 0101 is actually a 5 (0101 = 101 - zeros at left don't count)

Thanks alot for all the input guys. What i ended up doing was converting it to int and doing the addition that way.
