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

See them in action here.

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:

• https://github.com/Patashu/break_infinity.js/releases
• https://github.com/antimatter-dimensions/notations/releases

npm install @antimatter-dimensions/notations

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

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

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)

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 CancerNotation 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.

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 targets to the dist directory.

npm run build

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