Both Vince's and my code work good. What are you trying to accomplish anyway?

EDIT: Okay, I see "-,100,000,000". Replace with:

pawn Код:

for (new i = strlen(string) - 1, j = ((integer < 0) ? 1 : 0); i > j; --i)

and it'll be fixed.

EDIT 2: Or even better as Vince tip:

pawn Код:

IntegerWithDelimiter(integer, delimiter[] = ",")
{
    new
        string[16];

    format(string, sizeof(string), "%d", integer);

    for (new i = strlen(string) - 3, j = ((integer < 0) ? 1 : 0); i > j; i -= 3)
    {
        strins(string, delimiter, i, sizeof (string));
    }
    return string;
}
