Integers

The integer data type is a signed 32 bit value between −2,147,483,648 and +2,147,483,647 (that is 0x80000000 to 0x7FFFFFFF in hex). Integers are whole numbers. The fractional datatype is the float.

DEBUG_CHANNEL can be used as a constant for the maximum integer (for that is the value it is defined as).

Examples

All of the following are integers:

integer firstInt = 5512623;
integer secondInt = ACTIVE;
integer thirdInt = 0x61EC1A;
integer fourthInt = -160693;

The following are NOT integers, use float for them:

integer decimalValue = 125.2; // ERROR : Type mismatch -- Integer literals can't have a decimal.
integer bigValue = 3147483647; // An undocumented way to say -1,147,483,649 // Integer literals can't be larger than 2,147,483,647.
integer biggerValue = 10123456789; // An undocumented way to say -1 // Integer literals can't be larger than 2,147,483,647.

The following function can be used to determine whether a string of characters consists only of integers. This can be important if you need to know that a user has entered a valid integer in chat or a textbox, for example.

integer IsInteger(string var)
{
    integer i;
    for (i=0;i<llStringLength(var);++i)
    {
        if(!~llListFindList(["1","2","3","4","5","6","7","8","9","0"],[llGetSubString(var,i,i)]))
        {
            return FALSE;
        }
    }
    return TRUE;
}
