Bitwise Operations

[Stormeus]

Vortrex is wrong in his tutorial. 32 bits does not mean numbers can be 32 digits long. Both of you need to read a tutorial on binary.

The server is not "32-bit with 64-bit support." That statement is literally nonsense, it means nothing. The 64-bit server is compiled to only run on 64-bit computers and runs with 64-bit instructions.

I will let him know ....

Thanks Stormeus! that is the reply I was looking for..... I am happy I asked

[Stormeus]

To better answer your other question:

As in if I use a 32 bit server.exe then my limit is 32?
If I use a 64 bit server.exe then my limit is 64?

Yes, Squirrel on a 32-bit server will have 32-bit numbers, and Squirrel on a 64-bit server will have 64-bit numbers, so aside from mistaking bits with decimal places, you're pretty much right there.

It's also why if you compile a Squirrel file on a 32-bit server and try to run the compiled file on a 64-bit server, the script won't run: the compiled script is made for a different processor architecture.

I never knew that with compiled scripts

  Learning Something.
I am definitely going to take the time read a tutorial on binary!

I appreciate the kind responses and correct feedback. YET! pointing out reading into binary tutorials. Kudos!!!


Atleast I learned something with the studying I did,http://en.wikipedia.org/wiki/Bitwise_operation ...
But I am happy you stopped this learning process before I continued to think like this.

They are 32 and 64 respectively. That's why if you try to compile a plugin on 32 and run it on 64 you'll get the 0x0000007b

**I did not make this script, Or was it a normal release but just simply in an old random post.

Code Select Expand

// -------- Compiler Script --------
// ------ Created by VRocker -------

function onConsoleInput( cmd, text )
{
if ( cmd == "compile" )
{
if ( text )
{
local file = loadfile( "Scripts/"+text );
if ( file )
{
print( "Script " + text + " compiled successfully" );

writeclosuretofile( "Compiled Scripts/"+text + ".cnut", file );
}
else print( "Unable to load script " + text );
}
else print( "Error - Invalid arguments (compile <script>)" );
}
}
Due to the different exe builds, there will be a different outcome/support.. as Stormeus said?.

Probably not. It isn't converted to native machine code, just squirrel bytecode.

In 32 bit the maximum number held in a variable will be in 2^32. In 64 the limit is square of 32bit limit, or 2^64.
This is due to the fact that in one variable, what you have is a bunch of zeros, and you can change them to a 1. But the limitation is that you have a set amount of zeros.

well, that's all about integer. To be simple
For ex:
After 40 days of running the server, if you use GetTickCount it would return a wrong number on a x32 server since the integer would be too large to handle, more than 32 in length, it will take many months or even years on a x64 system.

No. It will count again from zero.

Haven't tested that cause from the start I'm with a x64 server, and also, we guys won't keep our server up for a extremely long time as 40 days, if we host at home

[Vortrex]

Well, at the time I made that post, I didn't have a lot of knowledge on how 32 bit integers worked.
I just knew how to use bitwise operators, so that's why I put the post up so people could also learn.

I've done some reading since and I'll probably edit the tutorial once I get some time later today.
It wasn't my intention to mislead anybody.
