String types
string
- LSL strings support UTF-8 characters.
- LSL string variables are limited to the amount of free memory available to the script.
- Other data types can be typecast into a string for use with llHTTPRequest(), llMessageLinked etc.
- The results of any communication operation that returns a string (listen, link_message, http_response, dataserver) can be typecast into the required data type.
key
- Key is the data type used to store UUID
- Although Second Life UUIDs adhere to a specific standard, the key data type itself can store any valid string.
Numeric types
float
- LSL Floats adhere to the IEEE 754 standard for floating point numbers.
integer
- In LSL, integers are 32-bit values ranging from -2147483648 to 2147483647.
- LSL does not have an unsigned integer type (which would allow for values between 0 and 4294967295)
- Integers can either be entered in decimal or hexadecimal
Examples
- integer foo = 10;
- integer bar = 0xa; // returns 10
- float bah = 10.0;
- integer foo = (integer)16.4; // returns 16
- float bar = 16.4;
