/LSL

Operator: +

Valid Types:

• Integer
• Vector
• Rotation
• String
• List

Integer

• Operation: Addition
  • Example:
    • 1 + 1
    • Result = 2

Note: If one variable or value is a float, the integer value will be cast to a float automatically.

Float

• Operation: Addition
  • Example:
    • 1.5 + 1.5
    • Result = 3.0

Note: If one variable or value is an integer, the integer value will be cast to a float automatically.

Vector

• Operation: Addition
  • Examples:
    • <1.0, 1.0, 1.0> + <1.0, 0.0, -1.0>
    • Result = <2.0, 1.0, 0.0>
    • Action: <a.x, a.y, a.z> + <b.x, b.y, b.z> == <a.x + b.x, a.y + b.y, a.z + b.z>
    • <-1.0, 0.0, 1.0> + 1.0
    • Result: <0.0, 1.0, 2.0>
    • Action: <a.x, a.y, a.z> + b == <a.x + b, a.y + b, a.z + b>

Note: All elements are floats, if any are written as integers they will be cast to floats automatically

Rotation

• Operation: unknown!

Note: This operator is rarely used with this type as it is not a meaningful way of combining quaternions being used to represent rotations. Use Multiplication instead.

String

• Operation: Concatenation (adds to the end of)
  • Example:
    • "abc" + "def"
    • Result = "abcdef"

Note: While Keys are a specialized type of String They cannot be directly used with this operator.

List

• Operation: Concatenation (adds to the end of)
  • Example:
  • [0, 0.0, <0.0, 0.0, 0.0>, ""] + [1, 1.0, <1.0, 1.0, 1.0>, "xyz"]
    • Result: [0, 0.0, <0.0, 0.0, 0.0>, "", 1, 1.0, <1.0, 1.0, 1.0>, "xyz"]
    • list + value = [contents_of_list, value]

Note: If the type of the variable or value being added to a list is not a list it will be cast to a list automatically

Notes

• needs link for article about min/max integer/float values
• needs link for article about max string and list lengths
• It'd be helpful if someone wrote a template for this page so that it might be abstracted to other operators after layout is finalized
  • this is only a sample layout, feel free to suggest other layouts.
