@ -9,10 +9,15 @@ Bug fixes
* Bug in `Position::is_beginning_of_line` is fixed.
Enhancements
New features
------------
* Comparisons between `FLOAT`/[`Decimal`](https://crates.io/crates/rust_decimal) and `INT` are now built in.
Enhancements
------------
* Built-in operators between `FLOAT`/[`Decimal`](https://crates.io/crates/rust_decimal) and `INT` are now implemented for more speed under those cases.
* Error position in `eval` statements is now wrapped in an `EvalAltResult::ErrorInFunctionCall`.
* `Position` now implements `Add` and `AddAssign`.
* `Scope` now implements `IntoIterator`.
