It’s not the brackets, I have a very plain value defined as a macro and it doesn’t work either.

#define DEFAULT_MARGIN 0.0001f

UCLASS()
class MYGAME_API UFloatHelpers : public UBlueprintFunctionLibrary
{
    GENERATED_BODY()

public:
    UFUNCTION(BlueprintCallable, Category = "Float Helpers", BlueprintPure, meta=(Keywords="float, equal, eq, ==", CompactNodeTitle="≈"))
    static bool EqualWithMargin(float A, float B, float Margin = DEFAULT_MARGIN);
}

Doesn’t work with #define DEFAULT_MARGIN 0.0001 either
