How do hexadecimal numbers or whatever work?

[Peter_20]

I recently learned that 65535 equals to FFFF in hexadecimal numbers or something; could you please tell me more on the subject?
How does it work?

When in doubt, ask the <a href=http://en.wikipedia.org>giant brains.</a>

Huh?
I don't understand.

When in doubt, and lost in that doubt, the giant brains will even direct the feeble minded to the appropriate node.

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.

Oh well, thanks, I guess.

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).

thanks, I do that all the time. Working with a BPM that counts it thusly: 1234567890abcdef; so now I am scarred for life.

It is like those lovely VB6 engineers who think array's start with 1

sides, it is all about the aquadrosexagesimal AKA, programmer foursomes.

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.

[Renmiri]

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.

Also known as Base-16.

Delusional little buggers that they are.

You didn't find a certain hexadecimal number that starts with 09 and ends with F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0?
