Subject: Round floats to N decimal places?

I'm doing some math that results in floats with ~10 decimal places,
but I'd like to round them to 2 places.  Is there a built in way of
doing this?  Right now I'm doing format("%0.2f", the_float).to_f,
which seems to work fine but it seems like an ugly way of doing it.

Thanks,
Pat
