What is $log( b,a)$ according to google?

Question

I expected that $log(b, a)$ represents $log_ba$. However this is not what google calculates for you if you type that into the search bar. For example, google says $log(4,2) \approx 0.62324929039$. What is it calculating in this case?

Answer 1

In google calculator, "," is mapped to "." and $log(b,a)$ represents $log_{10}{b.a}$
