Using C++ to make nodes to use in BP

Hi all

To summarise, i have been using C++ to be able to use the “double” variable type as a node in blueprints, but i have very little experience with C++

This is an example that allows me to add 2 strings together to get numbers larger than what a float or int would.

FString UUE4KitMathBPLibrary::Add_DoubleDouble(const FString& A, const FString& B)
{
	double A_double = FCString::Atod(*A);
	double B_double = FCString::Atod(*B);
	double C_double = A_double + B_double;
	return     UUE4KitMathBPLibrary::DoubleToString(C_double);
}

However i need to use branches in my BP to activate some things in game, how would i create a >= node that has a bool as a return value? Ive spent hours trying to manipulate the code shown but to no avail, and i have no idea where to start looking online.

Or if there is another way to use a branch type function without using bools, that would be useful too (the branches will be used to check if a variable is greater than or equal to another variable)

I have implemented a FDecimal class in a MIT plugin which code you can read from here:

There’s many operators overloading you can use as a reference.

thank you sir!! would i be able/allowed to change the FDecimal to Double?

also does it have maths nodes (such as “>=” ) with bool return values?
