data flow of while loop

[hrwang]

What's the data flow of a while loop?

Assuming I have a while loop and the operation result (a single number) is wired out as an output. My question is, what is the output, is it an array of numbers accumulated from each loop, or it is a single number of final loop?

Thanks

By default you get the last value. You can enable autoindexing on the tunnel (right-iclick...) and you'll get an array of all values from all iterations.
