h1. Scripting Operators

AdiIRC supports various operators for use in [[/if]] [[/else]] [[/elseif]] [[/while]] and [[$iif]] expressions.

[[/var]] [[/set]] [[$calc]] supports it's own set of [[Arithmetic Operators|arithmetic expression]].

All operators supports the "!" sign to reverse the operation. 

Operators in bold is AdiIRC only.

*Example*

<pre>
; check if 5 is lower than 4.
if (5 < 4) echo true
else echo false

; Reverse check if 5 is lower than 4 same, as 5 > 4.
if (5 !< 4) echo true
else echo false
</pre>
