<p><b>New page</b></p><div>One common [[comparison operator]] is the '''not equal to operator'''.<br />
<br />
This operator will return [[Boolean|true]] if the value on the '''left''' is '''different to''' the value on the '''right''' of the operator.<br />
<br />
== Syntax ==<br />
In most languages, the not equal to operator is represented by a <code>!=</code> symbol.<br />
<br />
== Equivalence to inverting the result of an [[equal to operator]] comparison ==<br />
These two code snippets generally return exactly the same result:<br />
<br />
<syntaxhighlight lang="java"><br />
boolean a = 5 != 3; // true<br />
boolean b = !(5 == 3); // also true<br />
boolean c = a == b; // true<br />
</syntaxhighlight><br />
<br />
== Comparison of different types ==<br />
Most [[programming language|programming languages]] (with the notable exception of [[JavaScript]]) will return [[boolean|false]] if the two values being compared are of a different type.<br />
<br />
For example, if we compare the number <code>5</code> with the string <code>"5"</code>, the result will be <code>false</code> because the values were of different types.<br />
<br />
<blockquote>See [[JavaScript equal to operator]] for info on how [[JavaScript]] handles the equal to operator(s).</blockquote><br />
<br />
== Example ==<br />
<syntaxhighlight lang="java"><br />
boolean a = 7 == 7; // true<br />
boolean b = 6 == 7; // false<br />
boolean c = 5 == "5"; // false... unless you're using JavaScript!<br />
</syntaxhighlight></div>Dylan
