Comparison Operators

Comparison operators in VectorScript are used to compare values of various types and return a Boolean value (true or false) result. The results of expressions using comparison operators are most often used to control the flow of script execution.

The table below summarizes the comparison operators available in VectorScript.

 

Operator	Operand	Precedence	Associativity	Operation
<	Number, STRING, CHAR	4	L-R	Less than
<=	Number, STRING, CHAR	4	L-R	Less than or equal to
>	Number, STRING, CHAR	4	L-R	Greater than
>=	Number, STRING, CHAR	4	L-R	Greater than or equal to
=	Any type	5	L-R	Equal to
<>	Any type	5	L-R	Not equal to

Less Than ( < )

The < operator evaluates as TRUE if the first operand is less than the second operand; otherwise it will evaluate as FALSE. Operands may be numbers, strings, or characters; strings are evaluated alphabetically, by character encoding.

Less Than or Equal To ( <= )

The <= operator evaluates as TRUE if the first operand is less than or equal to the second operand; otherwise it will evaluate as FALSE. Operands may be numbers, strings, or characters; strings are evaluated alphabetically, by character encoding.

Greater Than ( > )

The > operator evaluates as TRUE if the first operand is greater than the second operand; otherwise it will evaluate as FALSE. Operands may be numbers, strings, or characters; strings are evaluated alphabetically, by character encoding.

Greater Than or Equal To ( >= )

The >= operator evaluates as TRUE if the first operand is greater than or equal to the second operand; otherwise it will evaluate as FALSE. Operands may be numbers, strings, or characters; strings are evaluated alphabetically, by character encoding.

Equality ( = )

The = operator returns TRUE if its two operands are exactly equal, and returns FALSE if they are not equal. The operands may be of any type. For operands of type STRING, the values are compared on a character-by-character basis, and must contain exactly the same characters.

Inequality ( <> )

The <> operator tests for the exact opposite of the = operator. If two equal values are compared using the inequality operator, the resulting value will be FALSE. Comparison of two values which are not equal will yield a TRUE result.
