pi-digits

Calculate requested digits of Pi.

Building

Install stack, then run stack build from inside the repository.

Run stack exec pi-digits-exe, or execute the binary found in ./.stack-work/install/.

[X] Add a function for converting results to decimal (and binary).
[X] Implement threading.
[X] Implement optparse-applicative for more formal/extensive arg parsing.
[X] ~~Replace the mess in prompt with a monad.~~ Issue corrected by using optparse-applicative.
[X] Separate into different files. Possibly parsing and logic files.
[X] ~~Find a better way to transfer "globals", like delim and printFun.~~ parseIndex handles all parsing and calling logic now.
Implement a faster mod operation, to allow for larger numbers (like 12345678901234567890). It will likely be implemented with the algorithm explained in the paper.
Customize print behavior and frequency. Flush output every N digits, or something similar.
