# bc
|
|
|
|
A better basic calculator. Like the original `bc`, but with a better
|
|
prompt. Work in progress. Very incapable right now.

## What?
|
|
|
|
The idea behind `bc` is to display partial results to the right of the
|
|
cursor in yellow while we type. A little example can be found in the video
|
|
above. Minor syntactic cleanups have been developed as well (e.g. no `local`
|
|
keyword). We have infinite precision integers and 90 decimal mantissa precision
|
|
floats.
|
|
|
|
## TODO
|
|
|
|
- A good readline copy (haskeline is sadly out of the question for this project)
|
|
- Comment parsing
|
|
- Closures that can modify the parent environment (but do away with the `local` keyword).
|
|
- Better arbitrary precision floats
