[Tutor] Help on float & round.

[Decibels]

Bookmarked. Thanks.
While on the subject of float and round. I originally tried to make it
save the value as, 'rounded', to save it in a database.
That doesn't seem to work and I don't think there is a way to do so.
For accuracy sake it makes sense, just wondering if there was a way.

Printing format was the most important and that has been solved, thanks.
