If change the resolution, the error changes. Looks like +-1 index error
Although I'm not sure about it

+Hmm, no, there is still a lot of strange and unknown in the code, but it's not about indexing

++ The error does not decrease with increasing accuracy! It is minimum at minimum precision and is fixed at 100~
