Hash( <expression> )
Contents |
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.
println("Hash A: " . Hash("Hello") ); $lol = "o"; println("Hash B: " . Hash("He" . "ll" . $lol) );
