Build Status Hackage Hackage Dependencies

Extra type-level operations on GHC.TypeLits.Nat and a custom solver implemented as a GHC type-checker plugin:

  • GHC.TypeLits.Extra.Max: type-level max
  • GHC.TypeLits.Extra.Min: type-level min
  • GHC.TypeLits.Extra.Div: type-level div
  • GHC.TypeLits.Extra.Mod: type-level mod
  • GHC.TypeLits.Extra.FLog: type-level equivalent of integerLogBase# .i.e. the exact integer equivalent to "floor (logBase x y)"
  • GHC.TypeLits.Extra.CLog: type-level equivalent of the ceiling of integerLogBase# .i.e. the exact integer equivalent to "ceiling (logBase x y)"
  • 'GHC.TypeLits.Extra.Log': type-level equivalent of <https://hackage.haskell.org/package/integer-gmp/docs/GHC-Integer-Logarithms.html#v:integerLogBase-35- integerLogBase#> where the operation only reduces when "floor (logBase b x) ~ ceiling (logBase b x)"
  • GHC.TypeLits.Extra.GCD: a type-level gcd
  • GHC.TypeLits.Extra.LCM: a type-level lcm
