First go to http://www.shareordie.com/forum/index.php?showtopic=3269 to learn binary. OK, 1,453,752 is 101100010111010111000 is binary, now we turn it into a Hex number. First Hex numbers goes like this: 1=1 2=2 . . 9=9 10=A 11=B 12=C 13=D 14=E 15=F Now you need to take the first octet (the far right 4) and place it under this little grid: 8 4 2 1 -------- 1 0 0 0 = 8 See the 1 under the 8 column? That is what you add. So the next octet is 1011, put it under the grid: 8 4 2 1 -------- 1 0 0 0 = 8 1 0 1 1 = B See 8+2+1=11, so you can't just say 11 you have to put it in a Hex number, which is B. So the full Hex number of 1,453,752 is: 8 4 2 1 -------- 1 0 0 0 = 8 1 0 1 1 = B 1 1 1 0 = E 0 0 1 0 = 2 0 1 1 0 = 6 0 0 0 1 = 1 <-- Just add zero if it isn't a full octet 162EB8 So if you want to turn a number in to the shorter version of Hex, just turn it into binary, then use this grid and you'll do fine P.S. Thanks Korrupt for the number to work with
