Rounding for mass on engines

I'm not sure if I saw it anywhere in the Fleet Book, but when I ran the
calculations on existing designs, I think I figured it out, but I wanted to
double check...

When determining the size of Main Engines and FTL Drive, do you round down
less than 0.5 and round up 0.5 or greater?

For instance, a ship of Mass 14 requires an FTL drive which is 10% Mass. This
is 1.4...Rounded down to 1? This same ship requires a Thrust of 6, which is 5%
of Mass per Thrust, which is 4.2.... Rounded down to 4?

Thanks,

This is correct with one exception: an engine must have a mass of at least
1.

Correct, unless it would be rounded down to 0 - all systems on a ship
must have at least Mass 1. You saw it in FB1, section "Choosing Overall Ship
Mass" on p. 10.
