if formula Node

Go to solution



I am using a formula node and the IF Command to generate an output based on User Input. I have posted a couple of screenshots of the simplified version of my VI. Every time I get the last value. What am I doing wrong?

Hi rkamat,


don't use a formula node here…


- When your x value is always an integer you could use an array constant holding your Y values and use x to index the array…

- When your x value isn't an integer you could use the function Interpolate1DArray instead of IndexArray!


You also made a typo in your formula node. I'm sure the formula node doesn't like a comma as decimal separator!

Thanks! It worked. I work on the german version of Labview. Comma is the decimal separator in German

Hi rkamat,


I also work with a German WindowsOS, but I use the point as decimal separator…


You know you can change that setting?
