data-interval

Interval arithmetic for both open and closed intervals

Latest on Hackage:1.2.0

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Build Status Hackage

Interval datatype and interval arithmetic for Haskell.

Unlike the intervals package, this package provides both open and closed intervals and is intended to be used with Rational.

  • use extended-reals package for representing endpoints
  • add (experimental) comparison operators that produce witnesses: (<??), (<=??), (==??), (>=??), (>??)

0.6.0
