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: <lsl>integer firstInt = 5512623; integer secondInt = ACTIVE; integer thirdInt = 0x61EC1A; integer fourthInt = -160693;</lsl>
The following are NOT integers, use float for them: <lsl> 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. </lsl>
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. <lsl> 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;
}</lsl>
Here's a simpler solution for strings containing positive or negative decimal integers (values from −2147483648 and 2147483647 written without + sign, leading zeros, or thousands separators ',' ).
<lsl>
if ( (string) ( (integer) data) == data) llOwnerSay("'" + data + "' contains a valid integer");
</lsl>
