No, Bill has this right. If rounded correctly, 045 becomes 'runway 4' and
055 becomes 'runway 6'.

So why is it correct to round 045 down to 'runway 4' and 055 up to 'runway
6'?

Ah, because the REAL rounding rule, designed so that averages will not
become distorted high from rounding 1/2 up, is to round 1/2 to the
EVEN number.

I know of almost no teacher nor textbook that remembers this, much
less why it is so.
