This is not without danger. Then the method used to calculate the number
of options must be specified.
The correct way is to find the number of integers in a float range
[min...max] is
n = (int)(floor (max) - ceil (min)) + 1;
This does *not* give the same result as rounding min and max
and then taking the difference plus one.
But I'm very much in favour of requiring the host to supply integers only
to a switched port. If it is given two exact integers as a range, this
should be no problem. If it uses the correct widget, this will even
be automatic.
