A high-precision partially-symbolic calculator with support for units, derivatives, and more.
|
A high-precision scientific calculator with support for units, derivatives, and more.
|
||||||
|
|
||||||
This is nowhere near complete. Stay tuned.
|
**todo:** ~~Try the [web version!]()~~
|
||||||
|
|
||||||
|
Many features are missing, this is still under development.

# Features
|
||||||
|
- Extremely high precision
|
||||||
## Before For 1.0 release
|
- Uses a rational datatype when possible,
|
||||||
- Commands
|
- Uses a high-precision float when not.
|
||||||
- Documentation (usage)
|
- Pretty printing in prompt
|
||||||
- Documentation (comments)
|
- Makes expressions shorter and easier to understand
|
||||||
- Units
|
- **todo:** ~~Supports nearly all physical units~~
|
||||||
|
- ~~Accounts for units in calculations~~
|
||||||
|
- ~~Explicit conversion operator `->` or `to`~~
|
||||||
|
- **todo:** ~~Variable and function definitions~~
|
||||||
