Relational Operators

Relational operators allow of the comparison of objects.

The following table lists the available relational operators.

Operator	Description	Example
EQU	Tests the equality between two objects	2 EQU 2 will give true
NEQ	Tests the difference between two objects	3 NEQ 2 will give true
LSS	Checks to see if the left object is less than the right operand	2 LSS 3 will give true
LEQ	Checks to see if the left object is less than or equal to the right operand	2 LEQ 3 will give true
GTR	Checks to see if the left object is greater than the right operand	3 GTR 2 will give true
GEQ	Checks to see if the left object is greater than or equal to the right operand	3 GEQ 2 will give true

Example

The following code snippet shows how the various operators can be used.

Example of Relational Operators

@echo off 
set /A a=5 
set /A b=10 
if %a% EQU %b% echo A is equal to than B 
if %a% NEQ %b% echo A is not equal to than B 
if %a% LSS %b% echo A is less than B 
if %a% LEQ %b% echo A is less than or equal B
if %a% GTR %b% echo A is greater than B 
if %a% GEQ %b% echo A is greater than or equal to B

A is not equal to than B
A is less than B
A is less than or equal B
