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.

No runtime deps
