LSL Operators
From InWorldz Wiki
(Redirected from =)

Operators are used to cause an operation (or mathematical action) to be performed on one (such as !) or two operands. The easy and common example is 1 + 2 where 1 and 2 are operands, and the + is the operator.
This concept can be extended much further with LSL since operands can be variables with the special case of the assignment operators requiring that the left hand side be a variable.
Operator  Description  Usage Example  Comments 

( )  Parentheses  a * ( b + c )  b + c will be evaluated first as it is inside the parentheses. 
[ ]  Brackets  [q, 4, "that", 0.15]  Used to enclose a list. 
! ~ ++   LogicalNOT, BitwiseNOT, increment, decrement  counter++; !TRUE  
* / %  Multiply/dot product, divide, modulus/crossproduct  rollover = (count + 1) % 5  rollover will be the remainder; e.g., if count is 7, then the result is 3. 7 + 1 is 8, 8 divided by 5 is 1 with a remainder of 3. 
  Subtraction  result = something  2  Whatever value is stored in something, result will be that amount minus 2 
+  Addition, joining strings, concatenating lists  result = something + 2 msg = "Hello, " + name list = [1,2,3] + [4,5] 
Whatever value is stored in something, result will be that amount plus 2 If the string variable name is "Bob", msg will be "Hello, Bob" list will be [1,2,3,4,5] 
<< >>  Left shift, right shift  eight = 4 << 1;  
< <= > >=  Less than, less than or equal to, greater than, greater than or equal to  isFalse = ( 6 <= 4 )  as six is not less than or equal to 4, the equation will return FALSE, which will be stored in the variable isFalse 
== !=  Comparison equal, comparison not equal 


&  Bitwise AND  zero = 4 & 2; four = 4 & 4; 

^  Bitwise XOR  zero = 4 ^ 4 six = 4 ^ 2; 

  Bitwise OR  four = 4  4;
six = 4  2; 

  Logical OR  isTrue = ( FALSE  TRUE )  
&&  Logical AND  isFalse = ( FALSE && TRUE )  
= += = *= /= %=  Assignment operators  four = 4;  if another mathematical operation is indicated, that operation is carried out and the result is assigned. Thus, four += 2 will take the current value of four, add 2 to it and save the result in four.
