ghc-typelits-extra

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/base-4.17.0.0/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
