Quiz: Can you get your Add function to look like this?

[Darren]

Even though it's Thursday, today feels like Friday to me. So here you go, a LabVIEW quiz with no practical use whatsoever. 😛 Can you get an Add function to look like this?

This was a regular ol' Add that I dropped from Quick Drop/the palettes. Can anybody figure out what I did to get it to look like this?

Does the answer have something to do with the dynamic data type?

EDIT:

I got it to look the same as yours but I couldn't get it from quick drop.

Steps to reproduce:

• Drop a waveform constant
• Drop an Add node
• Connect the waveform to both inputs of the add node
• Disconnect the waveform from the add node
• Drop an numeric constant
• Connect the numeric to both inputs of the add node (top first)
• hit Ctrl-Z (undo)

Interesting....

If you wire up that it gives the not-all-wires-connected error. Show context help, click the "detailed help" link for it and doesn't show the "add" help, it goes to the help index 🙂

Okay this thing apparently has bugs all over it.  What is the intent of the error wires?  When are they supposed to be used?  Why do they turn red with X on them?

The error in/out nodes are for waveforms/dynamic data type. You cannot add two waveforms with a different dt for instance. Somewhere in the flags of this node there is probably a 'needs extra nodes' flag which isn't removed all that properly.

It doesn't spit out an error when I try that though (it just gives me back an empty waveform).
