Example Symbol comparison functions 002

 

 

Description

These examples use the comparison functions to do a case-sensitive comparison of two objects of the same type. A Boolean value is returned.

 

Details

Both symbols are equal.

(= Mary: Mary: ) Returns: true

In this example, lowercase "m" in the first symbol has a higher value in the ASCII table than uppercase "M", therefore the symbols are not equal.

(= mary: Mary: ) Returns: false

Lowercase "m" in the first symbol has a higher value in the ASCII table than uppercase "M", therefore the first symbol is greater than the second symbol.

(> mary: Mary: ) Returns: true

Lowercase "p" in the first symbol has a higher value in the ASCII table than lowercase "m", therefore the first symbol is greater than the second symbol.

(< paul: mary: ) Returns: false

Notes and Hints

If you prefer an integer resulting from the comparison (0 for equal, -1 for less than, and 1 for greater than),use the compare function
