All relational operators compare the values of the operands and return True (-1) or False (0) as the result. All relational operators are binary.
| < | Less than | A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. |
| <= | Less than or equal | A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. |
| > | Greater than | A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. |
| >= | Greater than or equal | A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. |
| = | Equals | A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. |
| <> | Not equivalent to | A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. |
| precedes | ASCII less than | Unlike the < operator no
attempt is made to make a numeric interpretation of the argument values
before the comparison. The operation returns true if the value to the
left of the operator has a text representation which, in ASCII comparison,
comes before the text representation of the value on the right. Example: ' 11' precedes ' 2' returns True compare this to: ' 11' < ' 2' returns False |
| follows | ASCII greater than | Unlike the > operator no
attempt is made to make a numeric interpretation of the argument values
before the comparison. The operation returns true if the value to the
left of the operator has a text representation which, in ASCII comparison,
comes after the text representation of the value on the right. Example: ' 23' follows ' 111' returns True compare this to: ' 23' > ' 111' returns False |
