Validating Said is a integer....within the valid scope of things.

Integers can't be larger than 2,147,483,647 or -2,147,483,647 But HOW do i validate them ?

CODE

listen( integer channel, string name, key id, string msg )
    {
            integer msg = (integer)msg;
           if ( msg >= -2147483647 & msg <= 2147483647)
        {
            llSay(0 , "It works");
        }
        else
    {
        llSay(0, "Not right at all");
    }
CODE


But it is not working... i always says it works:(  sooo please can someone assit me in this would be greatly appreciated..:)

Here's a link for you to check out:

Hope it helps!

When you declare integer msg = (integer)msg; I believe LSL is declaring a new value for msg and the default is 0... it doesn't know whigh msg you want to use, since you've used the variable twice.

Try integer number = (integer)msg; instead, or really any other variable name but msg.

For your own debugging you could also have it read it back to you: llSay(0, "the integer is " + (string)number);

Also note that if the msg captured in the listen cannot be made into an integer it will probably get made into a zero.

Which would pass the "msg >= -2147483647 & msg <= 2147483647" test in the original post, yeah... Something to keep in mind.

Well, phooey... Reviewing the link I posted earlier, it also doesn't handle negative numbers :)

How about casting the string to an int then back to a string and comparing that with the original string?

CODE

default
{
     state_entry()
    {
        llListen( 0, "", NULL_KEY, "" ); 
    }
    listen( integer channel, string name, key id, string msg )
    {
            string data = msg;
        if((llParseString2List(data, ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"], []) == []) && (data != ""))
        {
            llOwnerSay("Integer");
        }
        else
        {
            llOwnerSay("Not An Integer");
        }
           
    }
}
CODE


but 2 things..
 1. it don't accomidate neg numbers
 2. only goes to 7 digits:(

i kinda at a loss:(

Try..

CODE

listen( integer channel, string name, key id, string msg )
{
     integer i = (integer)msg;
     if ((string)i != msg)
     {
          // not an integer

So using Sindy's to check if it is something else then an integer and also checking if it is between the range you would end up with:

CODE
default {
	state_entry() {
		llListen(0, "", NULL_KEY, "");
	}

	listen(integer channel, string name, key id, string msg) {
		integer i = (integer)msg;
		if ((string)i == msg && (integer) msg >= -2147483647 && (integer) msg <= 2147483647){
			llSay(0, "It works");
		}
		else {
			llSay(0, "Not right at all");
		}
	}
}

Say "-42" and it will answer with "It works".
-42.5 will return "Not right at all"
outside of range will return "Not right at all"
and finally "cat" will return "Not right at all"

well sindy it worked and i thank you ...
CODE

default
{
state_entry()
    {
        llListen( 0, "", NULL_KEY, "" ); 
    }
listen( integer channel, string name, key id, string msg )
    {
        integer i = (integer)msg;     
            if ((string)i != msg) 
                {     
                    llOwnerSay("not integer");    
                }
            else
                {
                    llOwnerSay("yes integer");
                }
    }
}
CODE


That is the final result and works for 10 digits and Neg numbers... 
thnx for all the help ...

You're welcome, Saladin!

So using Sindy's to check if it is something else then an integer and also checking if it is between the range...

Not in-world where I can test but I was assuming that if you fed it something outside the range of a signed int, the integer cast would give you back a zero and fail the test.

Still have the script? Now I'm all curious what it'll say for 3 billion.. :)

Integers can't be larger than 2,147,483,647 and it won't work above that and it works on the negative side sindy so ur all good there:) GREAT work... it did what i wanted... i was tring to make sure there was a number that i could pick and put to a data for a channel that the person wanted but in the limits of that and the fact that they could only pick a number not a word or anything which would make the whole system fail:)

Ah nice, so what you posted is all that is necessary adn you don't need to check against the range also.

LSL1
-2147483648
returns:
"It works"

-2147483649
returns:
"Not right at all"

Bad news is that if you go outside of range in MONO it will throw and error. Time for another jira entry:

MONO
-2147483648
returns:
"It works"

-2147483649
returns:

ahahah no bounds checking in mono typecasts? I await the jira to vote on.



beware using the method

i = (integer)msg
if ((string)i == msg)

if there are any extraneous spaces in msg, they will be dropped when converting to integer, and then the comparison will still fail on valid data. not sure if any other characters would be ignored in this fashion on conversion to integer, but it's something to be aware of.

Regular expressions would make parsing of large integers (or floating point numbers, or vectors, lists, commands, web pages, whatever) MUCH easier. Go vote for https://jira.secondlife.com/browse/SVC-790 if you haven't, and help expand our toolset enourmously with only the addition of a couple new functions.

/me guesses they'll fix that before releasing MONO scripts into the wild.. While I'm guessing, I'll guess that trying to do (integer)"blahblahblah" will also throw some kind of invalid cast exception.
