It's not me, it's the programmer. He was disgusted that his algorithm produced garbage, which means, the error was unacceptable. Mat be it was 1%, may be 80%, I don't, that was his decision, that the result was unacceptable. The bug description assumes the problem was in the last bit, which means, he wanted precision higher than the machine precision.
