Core Function DiffCalc

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

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:

[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 -=

Remarks

None.

Example

// 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
