Log Function

Maybe I have missed something, but I think the LOG function under
PROCESS-MATH-LOG does not work correctly. I am trying to take the LOG10
of each of the pixels in my image. I am using the 32-bit float format.
For instance if my pixel value is 2.01 then the LOG of it returns 0.670
for that pixel. Shouldn't the correct LOG be 0.301? What am I missing
here?

Thanks for your help.
