You will only have 255 "ticks" of resolution regardless, so there is no reason to go into decimals.

If I understand the system correctly, the limitation is in the signal being put out by the controller. It may have changed recently, but I'm pretty sure that older servos (probably from before the mid-90's) were completely analog. Older hobby radios (and lower-end new ones) were also analog. This gives you whatever resolution you are mechanically capable of having.
My newer futaba radio has 10-bit resolution. The earlier digital futabas had 9-bit. Barring an ingenious marketing scam, this would imply that the servos themselves are capable of at least 10-bit resolution.
As for the IFI system, it'd be an interesting trick to increase the PWM signal resolution.
