ArcGIS Pro 3.0.2: How to calculate the Ln(x) with Arcade?

 

I observed that the Ln(x) is not available in the list of “Helpers”.

 

But mathematically, Ln(x) = 2.403 Log(x)

 

What is shocking is that the Log (x) in Arcade calculates the Ln(x) but not Log(x)

 

What could be the issue here?

Hi @JamalNUMAN 

I would recommend using the Python code for this, it looks like something is missing in the Arcade section and I would suggest raising this with your distributor to have it raised as an enhancement for future releases or raise this within the Esri Ideas page.

I have noticed that if you use Python and this function it should get you the desired outcome 

Using math.log10() gives you a logarithmic value as seen below 

 

If you use math.log() this will perform the inverse log giving you the natural log (Ln) 

I hope this has helped.

The Log() expression in Arcade is described to return the following 

"Returns the natural logarithm (base E) of a."
