Positions

A position (finance) definition with some good algebraic properties.

Example

Add positions as a dependency of your project.

```toml [dependencies] positions = "0.1.0"

rust_decimal is added to make the example code work,

but optional for using positions.

rustdecimal = "1.17.0" rustdecimal_macros = "1.17.0" ```

And then, you can try this codes.

```rust use positions::normal; use rustdecimalmacros::dec;

let h1 = normal((dec!(1.0), dec!(2.0))); let h2 = normal((dec!(2.0), dec!(3.0))); let h3 = normal((dec!(1.5), dec!(-4.0)));

assert_eq!(h1 + h2 + h3, normal((dec!(1.6), dec!(1.0), dec!(-0.4)))); ```
