[Tutor] precision?

[Shwinn Ricci]

When comparing a given value with a database of values, but allowing for
freedom due to variation at say, the thousandth digit, how does one
generalize the precision to this degree? I don't want to truncate, so is
there a round() function that takes into account what decimal place the
value (database value) needs to be rounded to?
