• CLog: type-level equivalent of the ceiling of integerLogBase# .i.e. the exact integer equivalent to "ceiling (logBase x y)"
• Log: type-level equivalent of integerLogBase# where the operation only reduces when "floor (logBase b x) ~ ceiling (logBase b x)"
• GCD: a type-level gcd
• LCM: a type-level lcm
