I have a data set where all values are exactly the same however labivew is not returning a standard deviation of 0 when I perform this calculation within a loop. Please see the attatched .vi . (Perhaps I am overlooking something obvious).
Solved! Go to Solution.

Computers cannot exactly represent floating point numbers. The standard deviation you are getting is such a small number, it is effectively zero. You could easily test to see if it less than some other very small number and set it to zero if you want.

Ok I thought it may be something like that. Cheers.
