MONEYTALKS PLUGIN -- UNREAL ENGINE 4

  • This Plugin implements data types to represent Decimals and Money values compatible with the Unreal Engine environment.

  • All Currency types introduced are IEEE 754 compliant, C++ Classes to represent accurate world currencies defined by ISO 4217.

  • The FDecimal type can store up to 10^24 (29 signed digits): 99,999,999,999,999,999,999,999,999,999;

  • The FDecimal struct can be used by both C++ and Blueprint objects and actors in Unreal.

  • Replication and Serialization are handled by converting from Decimal to a subset of TCHAR* packs to maintain precision.

  • Implementation is based on Intel RDFP Math Library: Copyright(C) 2011, Intel Corporation. All rights reserved.

How to Use (Blueprints):

  • Add new Property to Blueprint.
  • Change Property type to 'Decimal'.
  • Use operator nodes and operators from category 'Variables | Decimal'.

C++ Example:

PublicDependencyModuleNames.AddRange(new string[] {"Moneytalks","Core","CoreUObject","Engine","InputCore"});
UCLASS()
class MYGAME_API AMyPlayerState : public APlayerState
{

	GENERATED_BODY()
	
	AMyPlayerState();
	
public:

	virtual void BeginPlay() override;
	virtual void Tick(float DeltaTime) override;

	UPROPERTY(Category = "Test", EditAnywhere, BlueprintReadWrite)
	FDecimal MyDecimal;
	
};


void AMyPlayerState::BeginPlay()
{

	Super::BeginPlay();

	MyDecimal = MAX_DECIMAL;
	int32 MyInt = MAX_int32;

	if (GEngine)
		GEngine->AddOnScreenDebugMessage(0,100.f,FColor::Purple,FString::Printf(TEXT("25 Percent of %s is ::"),*MyDecimal.ToString()));
		GEngine->AddOnScreenDebugMessage(1,100.f,FColor::Purple,*MyDecimal.GetValueOfPercentage(DEC(25)).ToString());

		GEngine->AddOnScreenDebugMessage(2,100.f,FColor::Blue,FString::Printf(TEXT("%i out of %s is ::"),MyInt,*MyDecimal.ToString()));
		GEngine->AddOnScreenDebugMessage(3,100.f,FColor::Blue,*MyDecimal.GetPercentageOfValue(DEC(MyInt)).ToString());

		FString A, B, C;
		MyDecimal.Unpack(A,B,C);
		FDecimal DE; DE.Construct(A,B,C);

		GEngine->AddOnScreenDebugMessage(4,100.f,FColor::Green,FString::Printf(TEXT("UNPACK:::  %s A | %s B | %s C"),*A,*B,*C));
		GEngine->AddOnScreenDebugMessage(5,100.f,FColor::Yellow,FString::Printf(TEXT("CONSTRUCT:::  %s"),*DE.ToDecorated()));
}

void AMyPlayerState::Tick(float DeltaTime)
{

	Super::Tick(DeltaTime);

	MyDecimal--;
	const auto M = MyDecimal.ToCurrency(EDEC_DisplayFormat::PrefixWithSpace,TEXT("BRL"));

	if (GEngine)
		GEngine->AddOnScreenDebugMessage(-1,-1,FColor::Emerald,FString::Printf(TEXT("%s"),*M.ToString()),true,FVector2D(3,3));
