When in doubt, ask the giant brains.

A better response, quoted from wiki - In mathematics and computer science, hexadecimal, base-16, or simply hex, is a numeral system with a radix, or base, of 16, usually written using the symbols 0–9 and A–F, or a–f. For example, the decimal numeral 79, whose binary representation is 01001111, is 4F in hexadecimal (4 = 0100, F = 1111). IBM introduced the current hexadecimal system to the computing world; an earlier version, using the digits 0–9 and u–z, had been introduced in 1956, and had been used by the Bendix G-15 computer.
Well yeah, this is the basics. There are different systems of using hex. the wiki article seems to cover enough of em. lol
I hope this forum isn't turning into t3h sarcasm headquarters now. :eep:
Oh well, thanks, I guess. :choc2:
never.
Hex is simple you just count liek this:
1234567890ABCDEF
normally you would say:
12345678910111213141516
65535 equals to FFFF == false
Actually it's 0123456789ABCDEF. Hex is present because it's an organised way of representing groups of bits, specifically groups of four bits, since all zero's = 0 and all 1's are equal to F. If you had five bits it would have to go up to and past Z to represent it, and with three bits you need only go as far as 8 (which coincidentally there is a representation for in the form of Octagonal numbers which are Base-8).Quote:

You know how you count in base 10 (10, 100, 1000)
well in Hex you count in base 16 (16 , 32, 48, 64, etc)
ok?
Since there's no 16 since digits (0123456789) they have to add alphabets (0123456789ABCDEF)
So that's how hex works.
position 0 + 16 x position 1 + 16x16 x position 2...
255 will be
= 2 x 16 x 16 + 5 x 16 + 5
= 512 + 80 + 5
= 597
the same goes for numbers with more than 3 digits
4th digit x 16 x 16 x 16
5th digit x 16 x 16 x 16 x 16
so on...
How do you know about the hexadecimal system, Renmiri? It doesn't sound like a motherly thing to know.
Sound like a basic understanding, it seems.Quote:

EoFF is turning into a school or something recently. :bigsmile:
65536 = FFFF
16 x 16 x 16 x 16 = 65536
hexidecimal jsut reminds me of tetra master
She used to work for Motorola :pQuote:

CONSPIRACY!
it is the largest number that can be represented in binary countin - i think. So in that case 65535 is to binary what FFFFFF is to hex.
edit: That is prolly why max PMS are at that number levi. Programmers always run into that number on more structured (and powerful ) languages. This does not include VB developers. They are not programmers. :cool:
2^16 is 65536, so 65535 is the largest number you can store in two bits. 15 to store the digits and 1 to store the information about the file.
Yes. It's 256*256-1, or 2^16, while 256 is 2^8.Quote:

I like the Base-Π number system :p
