Thanx a ton people.Was really helpful

Your solution for defining output datatype works great! But why doesn't it work the same for inputs? When I try defining an input variable using "C code syntax" I get a message saying the variable is already defined.

I tried deleted the input connector and re-adding it after defining the variable datatype in the code. But I get the same message, "variable already defined". It makes for some strange looking code to define the output variable one way and the input variable another.

The data type of the input gets changed automatically when you wire a value to it. The limitation is that it has to be numeric. When you first create an input node it's set to double. If you connect a wire that has as its source an integer value then the input will change to blue to indicate it's an integer. You do not define the input variables inside the formula node. The input node acts as the declaration and definition of the variable.

I can't see why the output array is always zero in my case. When I checked the sum of the arrays inside the formula node I know they aren't zero. But I'm not able to take them out of the formula node.

How is Pful declared?

I bet it's not empty, but you've simply put numbers in index 21-36

Oh! You have hawk eyes! Thank you very much. I was looking for hours and couldn't see it...🙈

Thank you!
