Don't get pedantic - the USPTO obviously doesn't.

Rounding floating point numbers?
Authored by: Anonymous on Monday, April 01 2013 @ 08:20 AM EDT
The simple slide rule simply adds or subtracts the logs of
the mantissas and then presents the anti-log as the results.
In order to make get the correct answer one has to be able
determine the expected order of magnitude of the results by
keeping track of powers of 10 (place value) in their head or
by using pencil and paper. A very common error is to be
off by a power of 10 and can easily trap the unaware.

More sophisticated slide rules use log-log scales and can
perform trigonometric functions as well.

I'm sure others know much more on the topic than I.
