[10:22:40] --> Dejunai has joined #exult
[10:22:56] <Dejunai> wjp: you here, a quick simple question
[10:38:22] <Dejunai> anyone here? anyone know much about bitwise operands?
[10:38:50] <Dejunai> shouldn't value&3 be equivalent to value MOD 3
[10:39:12] <Sevalecan> ...
[10:39:18] <Sevalecan> huh?
[10:39:48] <Dejunai> huh?
[10:39:50] <Dejunai> heh?
[10:40:11] <Dejunai> I have piece of source code from exult... I am trying to understand it
[10:40:35] <Sevalecan> value = 0001
[10:40:45] <Sevalecan> 3 = 0011
[10:40:51] <Dejunai> the code as implemented works fine, but it would be nice to know I could do it on paper if I had to
[10:40:51] <Sevalecan> value & 3 = 0001
[10:41:55] <Dejunai> i dont understand the actual process of "&" and I hafta say that searching for "&" is tuff in any enviroment
[10:41:58] <Sevalecan> I'm extremely tired right now, so if my explanation sucks, then you'll have to ask someone else o_O
[10:42:06] <Sevalecan> eh
[10:42:08] <Sevalecan> ok
[10:42:08] <Dejunai> np
[10:42:13] <Sevalecan> & = bitwise AND
[10:42:20] <Dejunai> ok
[10:42:22] <Sevalecan> if two bits in the same position on each number are 1
[10:42:27] <Sevalecan> then that bit in the returned number is 1
[10:42:36] <Sevalecan> otherwise the bit will be 0 in the number returned from the operation
[10:42:56] <Dejunai> ok, but in the example only one value is given
[10:43:05] <Dejunai> what am I actuall comparing?
[10:43:11] <Dejunai> oh... value vs. 3
[10:43:12] <Sevalecan> ... I dont know o_O
[10:43:21] <Sevalecan> ive never read the exult code :p
[10:43:21] <Dejunai> value&3
[10:43:27] <Sevalecan> http://www.eskimo.com/~scs/cclass/int/sx4ab.html
[10:43:59] <Dejunai> value and 3 compares bitwise the value and then 0011
[10:44:12] <Dejunai> is that true
[10:44:31] <Dejunai> wait I can test it...

[10:45:32] <Dejunai> dam I get it now
[10:45:54] <Sevalecan> great \o/
[10:46:08] <Dejunai> Sevalecan: much much thanks
[10:46:29] <Sevalecan> you're welcome
[10:46:31] <Dejunai> some times code is like looking at a 3d pixel poster you hafta cock your head a squint for hours
[10:47:01] <Dejunai> but if some just tells you its a boat in the picture the vision occurs
[10:47:22] <Dejunai> ... any idea what I am talking about...?
[10:47:46] --> Baastuul has joined #exult
[10:47:58] <Dejunai> well, either way... much much thanks
[10:50:16] <-- Baastuul has left IRC (Client Quit)
[10:52:36] <Dejunai> I am certain I'll be back... thanks again
[10:52:39] <Sevalecan> ...
[10:52:42] <Sevalecan> yup\
[10:52:44] <Sevalecan> np
[10:52:47] <Dejunai> heh
[10:52:57] <Dejunai> those 3d dot posters
[10:53:27] <Dejunai> lots of dotz blur your eyes they make some sort of blurry image in 3d?
[10:53:37] <Dejunai> heh/nm
[10:53:40] <Sevalecan> I'm afraid I have no idea what you're talking about
[10:53:40] <Sevalecan> :p
[10:56:57] <Dejunai> it's ok, its fairly obscure reference... it's just that some boob some years ago figured out how to make a 3d image out lotz of dotz... if you cross your eyes and make a serious effort you can see the hidden 3d image
[11:04:39] <wjp> bitwise and with 3 is the same as mod 4
[11:05:56] <Dejunai> yes I see that now... and thanks for answering.. I was just being a bit'dunce
[11:06:32] <Dejunai> I was thinking it modified value, but of course it doesn't
[11:07:17] <Dejunai> last night I said it worked but I was confused... I am very very happy to report that I am no longer confused
[11:07:42] <Dejunai> thak you all, very much
