The 37 is a real kicker.
It it had been 35 and included 25 and 30, then perhaps ...
type distance is delta 5.0 range 10.0..35.0;
for delta'small use 5.0;
(I believe that is correct off the top of my head).
I've never used a fixed point type to represent an
equi-distance set of integers, but I guess it would
work.
