# Boolean operators in ColdFusion 8: NOT, AND, OR

In ColdFusion 8 one can use shortcuts to refer to three boolean operators: NOT, AND, OR

NOT can also be used to as !

AND can also be used as &&

OR can also be used as ||

`<cfset x = 10><cfset y = 30><cfoutput>x = #x#<br/>y = #y#</cfoutput><!--- Reverse the value of an argument. For example, NOT True is False and vice versa. ---><p><strong>Using NOT or !:</strong> Testing for !x eq y </p><cfif !x eq y>   x is not equal to y<cfelse>   x is equal to y</cfif><p><strong>Using AND or &&</strong>: Testing for x eq 10 && y eq 30</p><!--- Return True if both arguments are True; return False otherwise. For example, True AND True is True, but True AND False is False. ---><cfif x eq 10 && y eq 30>   x is equal to y<cfelse>   x is not equal to y</cfif><p><strong>Using OR or ||</strong>: Testing for x eq 10 || y eq 20</p><!--- Return True if any of the arguments is True; return False otherwise. For example, True OR False is True, but False OR False is False. ---><cfif x eq 10 || y eq 20>   One of the values is true<cfelse>   None of the values are true</cfif>`

This code yields the following output.

=======Start output=======
x = 10
y = 30

Using NOT or !: Testing for !x eq y

x is not equal to y

Using AND or &&: Testing for x eq 10 && y eq 30

x is equal to y

Using OR or ||: Testing for x eq 10 || y eq 20

One of the values is true

=======End output=======

The other boolean operators — XOR, EQV, IMP — continue to work as before.

## One thought on “Boolean operators in ColdFusion 8: NOT, AND, OR”

1. Jorrit says:

It looks kind of strange because you use them both.
<cfif x eq 10 && y eq 30>
x is equal to y
<cfelse>
x is not equal to y
</cfif>
Why not use:
<cfif x == 10 && y == 30>
x is equal to y
<cfelse>
x is not equal to y
</cfif>
and:
<cfif x != y>
x is not equal to y
<cfelse>
x is equal to y
</cfif>
