New page

<pre>
Hash( <expression> )
</pre>

=== Description ===

Generate a unique hash code for a string value

=== Parameters ===

==== expression ====

The expression to compute the hash of (this will use the string value of a given variable).

=== Return Value ===

Success: Returns a number above or below zero.

Failure: Returns 0.

=== Remarks ===

This function computes a Int64 hash to provide a bit more uniqueness than a regular Int32 hash.

=== Example ===

As you see here both strings produce the same hash yet they were constructed differently.

<syntaxhighlight lang="sputnik">
println("Hash A: " . Hash("Hello") );

$lol = "o";
println("Hash B: " . Hash("He" . "ll" . $lol) );
</syntaxhighlight>
