> "Runways, all runways, have a 2-digit number that represents the magnetic heading of the runway to the nearest 10 degrees. If the runway's heading is 265 — 274 degrees, then the runway number is 27 — always drop the last “0.” The opposite end of the runway is 180 degrees apart, so Runway 09 (90 degrees)."

As ever, “it depends”. Without knowing more about the context, I can only appeal to my aesthetic sense and intuition.

Given that the computer doesn’t care if it’s 9 or 09, I’d probably store the value as 09. That will be familiar and natural to a human pilot familiar with reading runway signs. Or an experienced technical writer used to documenting airport designs.
Don’t confuse the human is always a good design choice.
Be seeing you,
