First he ripped out my 64-bit fixed point arithmetic, and replaced it with `int128_t` - which works by using two hardware 64-bit ints!
My quick benchmarks showed me that this slowed all arithmetic down by a factor of about five.
But then, even worse, since he had no understanding of how computer arithmetic worked, all his intermediate calculations were in 64-bit floating point, which then got converted back into `int128_t`.
Of course, the product never came out.
