standardform-rs

Effortlessly operate on numbers like 2e19 or 2*10^4 and more with this Rust implementation of standard form. Simplify, convert, and manipulate large numerical expressions with ease.

Features

• Create and manipulate numbers in standard form.
• Perform arithmetic operations on numbers with different exponents.
• Easily compare numbers in standard form.
• Clone and debug derive implementations for StandardForm struct.
• Integrate it with num_traits crate as well.
• Standardform can be hashed as well using hash feature.
• Integrate with nom using nom feature.
• no-std available as well.
• Bindings to other languages available (enable 'lang name'` feature to use bindings).

Usage

Add this library to your Cargo.toml:

[dependencies]
standardform = "0.1.1" # Version  

To enable intergation it with num_traits , enable num feature:

[dependencies]
standardform = { version = "0.1.1" , features = ["num"] }

To enable hashing , enable hash feature:

[dependencies]
standardform = { version = "0.1.1" , features = ["hash"] }

To enable intergation it with `nom` , enable `nom` feature:

```toml
[dependencies]
standardform = { version = "0.1.1" , features = ["nom"] }

Then

use standardform::StandardForm;

fn main() {
    // Create a new StandardForm instance
    let number = StandardForm::new(2.0, 19);

    // Perform arithmetic operations
    let result = number * StandardForm::new(1.5, -3);

    // Compare numbers
    if result > StandardForm::new(1.0, 10) {
        println!("Result is greater than 1*10^108.");
    }
}

JavaScript Bindings

If you prefer not to build the JavaScript bindings yourself, you can download a pre-built version of the pkg directory from the releases page. Follow these instructions to use the pre-built 'js' bindings:

1. Download the pre-built pkg directory from the releases page.

2. Extract the contents of the downloaded archive.

3. Ensure your HTML file references the pre-built JavaScript file. Add the following script tag to your HTML file:

   <script type="module">
       import init , { StandardForm } from '/path-to-pkg/standardform.js';
   
       await init()
   </script>
   

   Replace '/path-to-pkg/standardform.js' with the correct path to the downloaded 'standardform.js' file.

4. Your library is now ready to be used in your JavaScript code.

In case you are using webpack , follow this guide

Here are the guides to use this code with different methods of deployment and integration

Note: While using pre-built bindings is convenient, it's recommended to build the bindings yourself if you plan on making changes to the Rust code, as explained below

JavaScript Integration

For seamless integration between Rust and JavaScript, this library supports WebAssembly (Wasm). Follow these steps to update bindings when the Rust code changes:

1. Ensure you have wasm-pack installed:

   cargo install wasm-pack
   

2. Build the Wasm package:

   wasm-pack build --target web --out-dir ./website
   

3. If you make changes to your Rust code, rebuild the Wasm package to update the bindings

This ensures that your JavaScript bindings stay synchronized with any changes made to your Rust code. Remember to update the bindings whenever you modify your Rust implementation to maintain a consistent integration between the two languages.
