Operators

The operators permitted in expression are:

Operators
Operator	Description	Precedence
-	Unary minus	highest
^	Powers and roots
*	Multiplication
/	Division
%	Percentage
+	Addition
-	Subtraction
=	Equal to
<>	Not equal to
<	Less than	lowest
<=	Less than or equal to
>	Greater than
>=	Greater than or equal to

Operators in expression having the same precedence associate left-to-right.

example:

=((-1 + X^2) * 3 - Y)/2

produces the result 21.5. ]

The equality, inequality, and relational operators yield 1 for true and 0 for false. An expression with value 0 tests logically false while one with any non-zero value tests true.
