Antimatter Dimensions Notations

NPM Codacy Badge

All the notations that are included in the current version of Antimatter Dimensions, and the upcoming Reality Update.

See them in action here.

Setup

CDN

The simplest way to use this package is to include these scripts in your HTML page:

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/break_infinity.js"></script>
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/@antimatter-dimensions/notations"></script>

You can also grab specific versions here:

npm

npm install @antimatter-dimensions/notations

There is no default export. The correct way to import notations is:

import * as ADNotations from "@antimatter-dimensions/notations";

Use

All the notations are included inside ADNotations object:

const scientific = new ADNotations.ScientificNotation();

The main method that notations provide is format(value, places, placesUnder1000)

  • value can be Decimal, number or string which you want to format
  • places is used to format mantissa when number is greater than 1000
  • placesUnder1000 is used to format the number when it is lesser than 1000
const scientific = new ADNotations.ScientificNotation();

// Outputs "1000.00"
console.log(scientific.format(1000, 2, 2));
// Outputs "1.00e100"
console.log(scientific.format("1e100", 2, 0));
// Outputs "1e100"
console.log(scientific.format(new Decimal(1e100), 0, 0));

You can configure some formatting aspects via ADNotations.Settings object:

const scientific = new ADNotations.ScientificNotation();

// Outputs "1e100,000"
console.log(scientific.format("1e100000", 2, 2));

// Outputs "1e100000"
ADNotations.Settings.exponentCommas.show = false;
console.log(scientific.format("1e100000", 2, 2));

// Outputs "Infinite"
ADNotations.Settings.isInfinite = decimal => decimal.gte(1e100);
console.log(scientific.format(1e101, 2, 2));

Configuration settings:

  • Settings.isInfinite - function that determines if a Decimal value is infinite (default is decimal => decimal.gte(Decimal.MAX_VALUE))
  • Settings.exponentCommas.show - show commas in formatted output (default is true)
  • Settings.exponentCommas.min - lower bound for exponent to be formatted with commas (default is 100000)
  • Settings.exponentCommas.max - upper bound for exponent to be formatted with commas (default is 1000000000)

Extend

Creating your own notations is very simple! Just extend base class Notation and implement the required methods get name() and formatDecimal:

class SimpleNotation extends ADNotations.Notation {
  get name() {
    return "Simple";
  }

  formatDecimal(value, places) {
    return `Mantissa: ${value.mantissa.toFixed(places)}, Exponent: ${value.exponent}`;
  }
}

You can also extend existing notations (like EmojiNotation does) and override other methods, but this is a more advanced case which you can figure out by looking at the source code of existing notations.

Community Notations

To use community notations, download community pack from the releases page. The community pack can be used separately from the base pack. To access community notations from your code, use ADCommunityNotations instead of ADNotations. Apart from that, the usage pattern is the same as with the base pack

If you want your notation to be publicly available via this library, you should start by adding your notation to a src/community folder and making a pull request with it.

After your PR is merged (which means that one of the maintainers decided that it is good enough), you can reach out to AD devs about adding it to a base game. There is no guarantee that it will be added, but all well-made notations will be available as a community pack.

Build

First, clone the repo

git clone https://github.com/antimatter-dimensions/notations.git
cd notations

Then install npm dependencies

npm install

And then run build command which will build all packs to the dist directory and to the docs directory.

npm run build

To build the AD pack or community pack separately, use build:ad or build:community command.

Contributing

  1. Be reasonable when commiting something.
  2. Be original when making a new notation.
