Calculator
A lightweight rust calculation parser. Only supports basic syntax, eg. no parentheses or functions beyond basic operators.
The current operators that are supported are
| Character used | Function |
|---|---|
+ |
Add to number |
- |
Subtract from number |
* |
Multiply number |
\ |
Divide number |
^ |
Use an exponent |
Example: 2^2+5 would be transformed into 9. It is pretty much just normal math syntax.
Just pass a string reference to the calculate function, and a 64 bit floating point number will be returned.
