Relational Operators
< Returns 1 if the left expression is less than the right expression, otherwise returns 0.
<= Returns 1 if the left expression is less than or equal to the right expression,
otherwise returns 0.
== Returns 1 if the left expression is equal to the right expression, otherwise returns 0.
!= Returns 1 if the left expression is not equal to the right expression, otherwise
returns 0.
>= Returns 1 if the left expression is greater than or equal to the right expression,
otherwise returns 0.
>
Returns 1 if the left expression is greater than the right expression, otherwise
returns 0.
Assignment Operators
= Substitutes the right expression into the left expression.
+= Substitutes the sum of the left and right expressions into the left expression.
−= Substitutes the difference between the left and right expressions into the left
expression.
*= Substitutes the product of the left and right expressions into the left expression.
/= Substitutes the quotient between the left and right expressions into the left
expression.
%= Substitutes the remainder of the quotient of the left and right expressions into the
left expression.
|= Substitutes the logical OR of the left and right expressions into the left expression.
&= Substitutes the logical AND of the left and right expressions into the left expression.
Functions

otherwise returns 0.
Comments
Text written from // to the end of the line are not evaluated. You can write comments after
//.
White Spaces
Any number of spaces or tabs can be inserted between a variable, constant, function, or
operator.
Limitations to Expressions
An expression can contain up to 256 elements such as variables, constants, functions,
and operators. An error will occur if an expression containing more than 256 elements is
selected.
