-- Pseudo-random distribution constant calculator.
--
-- The constants are calculated by numerically approximating the roots of
-- the function f(p) = p - p(c) via Newton-Raphson / bisection.
-- Calculating p(c) is easy: evaluate a polynomial and invert it.
--
-- For an explanation and visualization of the PRD algorithm, please see

    MurmurHash2, 64-bit versions, by Austin Appleby and placed in the public domain.
    The same caveats as 32-bit MurmurHash2 apply here - beware of alignment 
    and endian-ness issues if used across multiple platforms.

    Ported to Lua by ManuelBlanc (https://github.com/manuelblanc/).
    Requires a 64-bit bitwise operations library. Eg, https://github.com/ManuelBlanc/lua-bit64
