Changes

0.9.2 [2021.02.17]

  • Export (/=!) and (/=?) operators.
  • The build-type has been changed from Custom to Simple. To achieve this, the doctests test suite has been removed in favor of using cabal-docspec to run the doctests.

0.9.1 [2020.01.29]

  • Add Semigroup instances for the Interval types in Numeric.Interval, Numeric.Interval.Kaucher, and Numeric.Interval.NonEmpty. Add a Monoid instance for the Interval type in Numeric.Interval.

0.9 [2019.05.10]

  • Remove the Foldable instances for the Interval types from Numeric.Interval and Numeric.Interval.NonEmpty.

0.8.1

  • Support doctest-0.12

0.8

  • Eq and Ord instances are now structural
  • Deprecate elem and notElem in favor of member and nonMember
  • Add iquot, irem, idiv, and imod functions
  • Relax Fractional constraint in deflate to Num
  • Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-2.0, and makes the doctests work with cabal new-build and sandboxes.

0.7.2

  • Redundant constraint cleanup
  • GHC 8 support
  • Added a flag for building with ‘herbie’

0.7.1.1

  • Redundant import cleanup

0.7.1

  • Now compatible with GHC 7.10.1-rc1
  • Fixed a number of broken #if pragmas, fixing previously missing instances.

0.7.0.1

  • Removed a couple of unnecessary Fractional constraints.

0.7

  • Corrected the definition of mignitude.
  • Added a notion of distance between intervals

0.6

  • Added Numeric.Interval.Exception. For consistency, we tend to throw exceptions now instead of rely on NaN when working with empty intervals.

0.5.1.1

  • Misc doctest fixes.

0.5.1

  • Added interval to facilitate the construction of known non-empty intervals.

0.5

  • The default Numeric.Interval now deals more conventionally with empty intervals.
  • The old “Kaucher directed interval” behavior is available as Numeric.Interval.Kaucher.
  • Strictly Non-Empty intervals are now contained in Numeric.Interval.NonEmpty
  • Renamed bisection to bisect.
  • Added bisectIntegral.

0.4.2

  • Added clamp

0.4

  • Distributive Interval

0.3

  • Removed dependency on numeric-extras
