Well,

This is an API to extract any rational numbers to particular combinations of "9", "1", "7", "8" by using + - * / ^ sqrt() exp() ln() methods.

Using 9 1 7 8 was just an coincidence.

Anyway you can change the combination by modifying main.js and run

node ./main.js --export

to export cache.json.

I've tried C++ BFS method to solve but that's too slow.

So I used VibeCoding.
