Examples of DiscreteInterval

org.fishwife.jrugged.interval.DiscreteInterval
Representation of integer (long) intervals and associated arithmetic. This is useful for representing numbers with inherent measurement error or uncertainty; instead of a single value or a single value with a +/- error, we represent this as a range of values. One of the interesting properties of interval arithmetic is that errors are monotonically nondecreasing as you perform additional operations on them.
