A high-precision scientific calculator with support for units, derivatives, and more.
|
||
|
||
**todo:** ~~Try the [web version!]()~~
|
||
|
||
Many features are missing, this is still under development.
|
||
|
||
|
||
# Features
|
||
- Extremely high precision
|
||
- Uses a rational datatype when possible,
|
||
- Uses a high-precision float when not.
|
||
- Pretty printing in prompt
|
||
- Makes expressions shorter and easier to understand
|
||
- **todo:** ~~Supports nearly all physical units~~
|
||
- ~~Accounts for units in calculations~~
|
||
- ~~Explicit conversion operator `->` or `to`~~
|
||
- **todo:** ~~Variable and function definitions~~
|
||
- **todo:** ~~Easy history recall~~
|
||
- **todo:** ~~Sums and products~~

## **Operators, sorted by priority (high to low)**
|
||
|
||
| Operator | Syntax |
|
||
|---------------------------|----------------------|
|
||
| function application | `sin`, `cos`, etc |
|
||
| factorial | `!` |
|
||
| powers | `^`, `**` |
|
||
| implicit multiplication | `3π`, `3(2+1)`, etc |
|
||
| square root | `sqrt`, `rt`, `√` |
|
||
| negation | `-3`, `-(1 + 2)` |
|
||
| modulo (short) | `%` |
|
||
