calc_engine
This Engine transforms a string representation of a Math expression to the actual result of the expression.
I'm using the top-down recursive descent parsing techque. (Input is read from Left -> Right)
How to use.
use calc_engine;
func main() {
let res = calc_engine::calculate("1 + 1")?;
let error_margin = f64::EPSILON;
assert!((result - 2.0).abs() < error_margin);
let res = calc_engine::calculate("(1 + 1) + 3")?;
}
Still to be done
- Bug fixes
- Logarithmic expressions
- More tests..
Not in any particular order.
