And having considered this further, IMHO it may indeed be better (if we use
the sign_traits approach) to build exclusively towards -Inf, since then you
don't need a count, simply subtract from 0 instead of adding.
Alternatively, one could continue with the {1, 2, 3, 4, 5} specializations
from least to most as above and instead of subtracting from MAX we again
subtract from 0 but negate the result of the subtractions.  Either way its
all just implementation details.
