found that you can also get more precision by keeping the decimal point and adding a bunch of zeros:

I learned something from your posting. Thank you.

I thought from previous experiments that WolframAlpha didn't understand assignments to variables.
Perhaps I was wrong or perhaps this is something new that has been added.

If it is new then I wonder if there is a page where new features are announced?
