+Rep who help me

NVM ~FIXED ~ by myself

pawn Код:

stock IsNumeric(const string[])

    }
    new length = strlen(string);
    if(!length) return false;
    for(new i = 0; i < length; i++)

Hello!

Either you rename the first function or you delete one of them.

Re: IsNumeric Problem !! Fast help - ihatetn931 - 09.05.2015

You can't have 2 functions with the same name, You need to change the name on one of them.

I was to slow someone beat me to it

Re: IsNumeric Problem !! Fast help - Sawalha - 09.05.2015

as the guy above me said, rename one of them or remove.

Re: IsNumeric Problem !! Fast help - J4Rr3x - 09.05.2015

Delete both and use this

pawn Код:

IsNumeric(const string[])
{
        for (new i = 0; i < strlen(string); i++)
                if (string[i] > '9' || string[i] < '0') return 0;

        return 1;
}

Why you aren't write it like this?

PHP код:



stock IsNumeric(const string[])

{

    new length = strlen(string);

    if(!length)return 0;

    for(new i;i<length;i++)

    {

        if(string[i] > '9' || string[i] < '0')return 0;

    }

    return 1;

}

Your fixed code won't be work. Take mine.

Okay, I really don't see the point in flipping the if statement around lol?!

Re: IsNumeric Problem !! Fast help - SickAttack - 09.05.2015

Supports negative and positive numbers. It breaks the loop if false and then returns the state of the function's purpose afterwards.

pawn Код:

IsNumeric(const string[]) 
{
    new length = strlen(string), bool:cancel = false;
    if(!length) return false;

    for(new i = 0; i < length; i ++) 
    {
        if((i == 0) && string[0] == '-' || string[0] == '+') continue;
        else if(string[i] > '9' || string[i] < '0')
        {
            cancel = true;
            break;
        }
    }

    if(cancel) return false;
    return true;
}

Don't really see the need for those extensive functions. Your script will most probably use sscanf and in that case you can simply get away with:

pawn Код:

IsNumeric(const string[]) return !sscanf(string, "{d}");

snip snop

if(string[i] > '9' || string[i] < '0') is the exact same as if(string[i] < '0' || string[i] > '9')

Same way that 8x5 is the same as 5x8

So both of his functions do the same thing but he just wasted time posting here
