Interval datatype, interval arithmetic, and interval-based containers for Haskell.
Unlike the intervals package,
this package provides both open and closed intervals and is intended to be used
with Rational.
Changes
2.1.0
introduce operations for Allen’s interval algebra (#18, thanks to marcosh)
make recip precise when 0 is not an interior point (#21)
add instance Storable for Interval (#25)
add instance Floating for Interval (#26)
2.0.0
change internal representation of Interval and IntegerInterval to
reduce memory footprint (#7, thanks Bodigrim)
introduce Boundary type (#10, thanks Bodigrim)
export isSingleton function for Interval and IntegerInterval (#13)
remove deprecated EndPoint data type (#14, thanks Bodigrim)
1.3.1
support lattices-2.0 (Thanks to Bodigrim).
move definitions of Interval and IntegerInterval data types into
internal modules and abstract away representations from the rest of
modules (Thanks to Bodigrim).
add new function mapMonotonic to Data.Interval and Data.IntegerInterval
add new function isConnected to Data.Interval.
1.2.0
add Data.IntegerInterval
use extended-reals >=0.2
EndPoint is deprecated. Use Extended instead.
1.1.1
remove unnecessary Real constraint from comparison operators.
1.1.0
remove unnecessary Num constraint from bunch of constructors and operations:
interval, (<=..<=), (<..<=), (<=..<), (<..<), whole, empty,
singleton, intersection, intersections, hull, hulls.
Thanks to Tad Doxsee for pointing out that.
1.0.0
use extended-reals package for representing endpoints
add (experimental) comparison operators that produce witnesses:
(<??), (<=??), (==??), (>=??), (>??)
0.6.0
add hulls, intersections :: (Num r, Ord r) => [Interval r] -> Interval r
fix a bug of (<=?) operator
0.5.0
fix dependency issue with QuickCheck and test-framework-quickcheck2
0.4.0
add simplestRationalWithin :: RealFrac r => Interval r -> Maybe Rational
