Additional type-level operations on 'GHC.TypeLits.Nat':

* 'Max': type-level
<http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:max max>

* 'Min': type-level
<http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:min min>

* 'Div': type-level
<http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:div div>

* 'Mod': type-level
<http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:mod mod>

* 'FLog': type-level equivalent of
<https://hackage.haskell.org/package/integer-gmp/docs/GHC-Integer-Logarithms.html#v:integerLogBase-35-
integerLogBase#> i.e. the exact integer equivalent to 'floor (logBase x y)'

* 'CLog': type-level equivalent of /the ceiling of/
<https://hackage.haskell.org/package/integer-gmp/docs/GHC-Integer-Logarithms.html#v:integerLogBase-35-
integerLogBase#> i.e. the exact integer equivalent to 'ceiling (logBase x y)'

* '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)'

* 'GCD': a type-level
<http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:gcd gcd>

* 'LCM': a type-level
<http://hackage.haskell.org/package/base-4.8.2.0/docs/Prelude.html#v:lcm lcm>

And a custom solver for the above operations defined in
'GHC.TypeLits.Extra.Solver' as a GHC type-checker plugin. To use the plugin,
add the

' OPTIONS_GHC -fplugin GHC.TypeLits.Extra.Solver '

pragma to the header of your file.
