old_oc'er Posted September 19, 2004 Posted September 19, 2004 I need help on how to understand the decimal value of the binary number. Can someone possibly help me? Share this post Link to post Share on other sites More sharing options...
Coolzero101 Posted September 19, 2004 Posted September 19, 2004 Binary is a lanquage of yes or no, 1 = yes 0 no, 1 bit 1 value, and there are 8 octets possible in one bit. Which when you have 8 1's and 0's it looks like this 11111111 = 256 128X1 + 64X1 + 32X1 + 16X1 + 8X1 + 4X1 + 2X1 + 1 X1 1 1 1 1 1 1 1 1 Those place values apply to create your value Here is the numer 128 and how it would look 128X0 + 64X1 + 32X1 + 16X1 + 8X1 + 4X1 + 2X1 + 1 X1 0 1 1 1 1 1 1 1 Because the first octet is 0 that 128 doesn't exist the overall value is 128. If you want to get into hext hex is just a 16 based code used to simplify binary, like in Ipv6, or a mac adress 0 = 0 1 = 1 2 = 2 3 = 3 4 = 4 5 = 5 6 = 6 7 = 7 8 = 8 9 = 9 10 = A 11 = B 12 = C 13 = D 14 = E 15 = F Even though it goes to 15, the 0 counts so its 16. That is as far as the simplification needs to go to keep 256 digits at 2 digits. i might edit this post to make it more understandable later.

DECwakeboarder Posted September 19, 2004 Posted September 19, 2004 Binary is really easy once you pick up on it, not to make ya'll feel bad, but some of the worst students in my C++ class picked up on binary Share this post Link to post Share on other sites More sharing options...
