Runway Designations rounding up / down

Hi chaps, noticed that the cross runway at Glasgow was redesignated from Runway 10 / 28 to 09 / 27 due to magnetic drift. Understood that, so far so good. However on the chart below, http://www.ais.org.uk/aes/pubs/aip/p...s/32PF0201.PDF

the magnetic headings are 096 / 276 degrees.
Why then is the designation rounded down?

If it is embarrasingly obvoius please feel free to point and laugh but I have googled well on this one.....

cheers
