If only the < operator is used, it returns the TRUE if code block 1 is less than code block 2, otherwise, returns FALSE.

If an = operator is appended to the < operator, it returns the TRUE if code block 1 is less than or equal to code block 2, otherwise, returns FALSE.

If a 'u' is appended to the operator, it treats the two code blocks as unsigned integers.

Syntax

< code block 1 code block 2
<= code block 1 code block 2
<u code block 1 code block 2
<=u code block 1 code block 2
