Related notes:

For scalar values, suggest:

"then a presentation processor must use the closest supported value unless computed value is equidistant from two supported values, in which case the processor must use the closest highest supported value."

For <color>, suggest

(i) treating alpha as a scalar, separately from rgb
(ii) for <rgb>, "then a presentation processor must use the nearest supported value of <rgb> in the euclidian (r,g,b) space unless the computed value is equidistant from two supported values, in which case the processor must use the one of the two supported values farthest from (0,0,0) in the euclidian (r,g,b) space."

suggest "the one of the two supported valued that is closest to +infinity" instead of "closest highest supported value" (i.e. Round half up)
