ember-short-number

ember-short-number

Short number formatting based on CLDR locale data. Particularly useful for statistical data, showing financial numbers in charts, and abbreviating number of ratings across a range of languages.

• 1234 is converted to 1K in English
• 101234 is converted to 101K in English and 101.1K if need 1 significant digit
• 1234 is converted to 1 mil in Espanol
• 101234 is converted to 101,1 mil in Espanol if need 1 significant digit
• 1234 is converted to 1234 in Japanese

Utilizes cldr-numbers-full. Here is the related proposal for Compact Decimal Format that this addon is based on. This is why there are no browser API's baked into something like Intl.NumberFormat.

Lastly, this work will be built into ember-intl in the near future and will use something like shortNumber notation style defined in ICU message syntax.

Installation

ember install ember-short-number

Configuration

Provide list of language codes applicable to your app in your environment.js file. See ISO 639-1 for more information.

If not provided, we will include the data for all CLDR number formatting options in your app. IMPORTANT - this adds ~28KB gzipped to your app so be sure to include all the languages you care about.

let ENV = {
  'ember-short-number': {
    locales: ['en', 'es'],
    threshold: 0.05 // default
  }
}

threshold

This configuration option decides when to round up the formatted number. So if you pass 95001, ember-short-number will output 100K. However, if you pass 94999, you will get back 95K.

Usage

The following APIs take the language code as the the second argument based on ISO 639-1. You can also pass en_GB and we will normalize it to en-GB as well.

Template Helper

{{short-number 19634 "en"}}
// 19K

{{short-number 19634 "en" significantDigits=1}}
// 19.6K

{{short-number 19634 "es-MX" significantDigits=1}}
// 19,6 mil

{{short-number 101K "en" significantDigits=1 financialFormat=true}}
// 0.1M

Service API

this.shortNumber.format(19634, 'en');
// 19K

this.shortNumber.format(19634, 'en', { significantDigits: 1, minimumFractionDigits: 1, maximumFractionDigits: 2 });
// 19.6K

this.shortNumber.format(101, 'en', { significantDigits: 1, financialFormat: true });
// 0.1M

this.shortNumber.format(19634, 'ja');
// 2万

this.shortNumber.format(19634, 'es', { significantDigits: 1 });
// 19,6 mil

• Note when using significantDigits, this addon utilizes toLocaleString.

Long Formatting

"Wait, I thought this addon was for compact number formatting?" Well it can be a misnomer depending on the language. Let's look at some examples.

This doesn't seem shorter!!!! (╯°□°）╯︵ ┻━┻

this.shortNumber.format(101000, 'en', { long: true });
// 101 thousand

But this does! ʘ‿ʘ

this.shortNumber.format(101000, 'ja', { long: true });
// 101万

So we will just go with ember-short-number for now.

Other

Currently this only shortens with latin digits 0..9
