Example String comparison functions 001

 

 

Description

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

 

Details

Both strings are equal.

(= "Hello World" "Hello World" ) Returns: true

In this example, lowercase "h" in the first string has a higher value in the ASCII table than uppercase "H", therefore the Strings are not equal.

(= "hello world" "Hello World" ) Returns: false

Lowercase "h" in the first string has a higher value in the ASCII table than uppercase "H", therefore the first String is greater than the second String.

(> "hello World" "Hello World" ) Returns: true

Lowercase "i" in the first string has a higher value in the ASCII table than lowercase "e", therefore the first String is greater than the second String.

(< "Hi World" "Hello World" ) Returns: false

Notes and Hints

The comparison functions are case-sensitive. For case-insensitive comparisons see the StringCiEQ, StringCiNE, etc. functions.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.
