log10 used in a formula node

[AlanSpectrumControls]

I am trying to create a formula using log10(X) in a formula node.  I can enter log(X) with no errors, but when I enter log10(X) I get an error.  How do I use log10 in a formula node?  Is log(X) actually log10?

Hi Alan,

by reading the context help of the formula node ("click for more help" ) I found: log(x) is base10, otherwise you may use ln(x) or log2(x).

Log is typically base 10, test it in some code to find out.

I ran into this a while ago. There are two different contexts in LabVIEW that give different meanings to the logarithm functions, re what the base is. I think maybe one context is mathscript and the other is formula nodes. If you get the documentation for one when you are doing the other things make little sense.

I think maybe they just change which base "log" refers to and how to specify the other base.
