How would I implement this aloroghithm in LUA?

I’m not sure what you mean by this.

This states that it uses the “XSH-RR variant of the PCG family.”

You can even check out the source code for yourself

                for (i = 2; i <= n; i++)
                {
                    double d = luaL_checknumber(L, i);
                    if (d > dmax)
                        dmax = d;
                }
                lua_pushnumber(L, dmax);
                return 1;
            }
            
            
static int math_random(lua_State* L)
            {
                global_State* g = L->global;
                switch (lua_gettop(L))
                { /* check number of arguments */
                case 0:
                { /* no arguments */
                    // Using ldexp instead of division for speed & clarity.
                    // See http://mumble.net/~campbell/tmp/random_real.c for details on generating doubles from integer ranges.
                    uint32_t rl = pcg32_random(&g->rngstate);
                    uint32_t rh = pcg32_random(&g->rngstate);
