log(x) calculator in Stata - simple!

[patrick handcock]

Hi all. Apologies in advance if this is a terribly simple query (new to Stata), but it has been bugging me... I imagine it will have a very quick answer.

I am trying to generate the log of a bunch of glucose values (e.g. log(glu), but the command doesn't seem to give me the answer I would expect.

e,g:

di log(4.8)
= 1.5686159

However when I calculate log(4.8) on calculator I get 0.68124 (e.g. http://www.webconversiononline.com/l...ype=log&of=4.8 )

Trying to figure out why the Stata result seems to be different... am I putting in the command incorrectly, or misinterpreting log?

Thanks in advance!

Patrick

On the web page you referred to, change the function to nLog (Natural Log). It gives you

Value of nLog(4.8) = 1.56861592
