Module documentation for 0.2.1
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/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
0.2.1 September 29th 2016
- Reduce
Max n n to n
- Reduce
Min n n to n
0.2 August 19th 2016
- New type-level operations:
Max: type-level max
Min: type-level min
Div: type-level div
Mod: type-level mod
FLog: floor of logBase
Log: exact integer logBase (i.e. where floor (logBase b x) ~ ceiling (logBase b x) holds)
LCM: type-level lcm
- Fixes bugs:
CLog b 1 doesn’t reduce to 0
0.1.3 July 19th 2016
- Fixes bugs:
- Rounding error in
CLog calculation
0.1.2 July 8th 2016
- Solve KnownNat constraints over CLog and GCD, i.e., KnownNat (CLog 2 4)
0.1.1 January 20th 2016
