<pre>
DiffCalc( <first>, <second>, <useDouble> )
</pre>

=== Description ===

Calculate the difference between two values and return the diff type Same/Add/Sub with a raw diff which can be added to the base value to make it become the second and a non-raw diff that must be added or subbed for first to become second

=== Parameters ===

==== first ====

The first value to calculate (source value).

==== second ====

The second value to calculate (destination value).

==== useDouble ====

Optional; If TRUE then the calculation will be made using Double instead of Int64

Default: False

=== Return Value ===

Success: A three element array with the following:
<pre>
[0] = Type (Same/Add/Sub)
[1] = Difference (to be used with Type so if type if Sub you -= the difference
[2] = Raw Difference can be applied directly to the first value with += or -=
</pre>

=== Remarks ===

None.

=== Example ===

<syntaxhighlight lang="sputnik">
// get a diff on double using the double flag
PrintDiff(100.0, 50.0, true);
// now get the diff on some ints
PrintDiff(0x411C88, 0x40230F);
PrintDiff(0x40230F, 0x411C88);

Function PrintDiff($first, $second)
{
// Get the diff
my List($Type, $Diff, $RawDiff) = DiffCalc($first, $second);
// Print its info
say "Type: $Type | Diff: $Diff | RawDiff: $RawDiff";
// To make the second from first we do
my $remade = $first + $RawDiff;
say "Remade: " . $remade . " | InHex: " . Hex($remade);
}
// PRINTS
// Type: Sub | Diff: 50 | RawDiff: -50
// Remade: 50 | InHex: 32
// Type: Sub | Diff: 63865 | RawDiff: -63865
// Remade: 4203279 | InHex: 40230F
// Type: Add | Diff: 63865 | RawDiff: 63865
// Remade: 4267144 | InHex: 411C88
