Operators - NEAT Portal Wiki

The following symbols are characters that specify how to combine, compare, or modify the values of an expression. These will be used in performing math operations, setting variables, and comparing operators or variables in conditional statements (ifgoto, ifgosub).

Arithmetic

Symbol	Name	Description
+	addition	Adds numeric expressions.
--	decrement	Subtracts 1 from the operand. ** Not implemented yet
/	division	Divides expression1 by expression2.
++	increment	Adds 1 to an expression. ** Not implemented yet
MOD	modulo	Calculates the remainder of expression1 divided by expression2.
*	multiplication	Multiplies two numerical expressions.
-	subtraction	Used for negating or subtracting.

Comparison

Symbol	Name	Description
==	equality	Tests two expressions for equality.
>	greater than	Compares two expressions and determines whether expression1 is greater than expression2; if it is, the result is true.
>=	greater than or equal to	Compares two expressions and determines whether expression1 is greater than or equal to expression2 (true) or expression1 is less than expression2 (false).
!=	inequality	Tests for the exact opposite of the equality (==) operator.
<	less than	Compares two expressions and determines whether expression1 is less than expression2; if so, the result is true.
<=	less than or equal to	Compares two expressions and determines whether expression1 is less than or equal to expression2; if it is, the result is true.

Assignment

Symbol	Name	Description
=	assignment	Assigns the value of expression2 (the operand on the right) to the variable, array element, or property in expression1.

Examples:

// Testing two numbers using comparison
ifgoto (1 != 2) doesnot
echo "They are equal!"
end

label doesnot
echo "They are not equal!"
end

Result:
17:25:54 They are not equal!
17:25:55 Script stopped

//Setting a variable called myVar and giving it a value of 1.
myVar=1
echo "My variable is " + myVar

Result:
17:47:31 My variable is 1
17:47:32 Script stopped

// Math!
myVar=2
echo 10 * myVar

Result:
17:49:02 20
17:49:03 Script stopped
