I have little experience with fixed-point types, but I think "digits 4" 
should actually be enough in this case (-40.0 .. 120.0). At least the 
code works with "digits 4", too. Anyway, Gnat says the minimum 'Size of 
the type is 12 bits in both cases, so I guess the variables have the 
same size and arithmetic the same speed in both cases (except, perhaps, 
if we multiply or divide two values of this type, but this example code 
does not do that.)
