Log (10) or ln?

Hi, it is always good to search the community before asking any question. Almost all questions have been asked before, like yours.

The 'log' in app inventor is actually ln()

I am making a game that requires showing huge numbers. So instead of 128123000000000000000000000000000000000 it will be shown as 128.123 undecillion. To do that, I need to use a base 10 log function, but the ‘log’ in the app inventor is actually ln(). Is it a bug or is it supposed to be like that, a base-e log instead of a normal base-10 log?
