var adapter = require('bigjs-adapter'); // See adapters section for full list var Decimal = decimalFactory(adapter); Decimal.getPrecision(); // => 20 new Decimal('1').div(new Decimal('3')).valueOf(); // => '0.33333333333333333333' Decimal.setPrecision(5); new Decimal('1').div(new Decimal('3')).valueOf(); // => '0.33333' ``` ### Operations ```js new Decimal('0.1').plus(new Decimal('0.2')).valueOf(); // => '0.3' new Decimal('0.3').minus(new Decimal('0.1')).valueOf(); // => '0.2' new Decimal('0.6').times(new Decimal('3')).valueOf(); // => '1.8' new Decimal('0.3').div(new Decimal('0.2')).valueOf(); // => '1.5' new Decimal('1').equals(new Decimal('1')); // => true new Decimal('1').equals(new Decimal('2')); // => false ``` ### toString, valueOf and toJSON ```js var decimalThird = new Decimal('1').div(new Decimal('3')); // with bigjs-adapter (other adapters might have differing implementations) decimalThird.toString() === decimalThird.valueOf() === decimalThird.toJSON(); // => true Number(decimalThird); // => 1/3 ``` ### JSON.stringify and JSON.parse with reviver ```js var Decimal40 = decimalFactory(adapter); Decimal40.setPrecision(40); var decimalThird = new Decimal40('1').div(new Decimal('3')); var stringified = JSON.stringify(decimalThird); // => '"0.3333333333333333333333333333333333333333"' JSON.parse(stringified, Decimal40.reviver); // => new Decimal40('0.3333333333333333333333333333333333333333') ``` See [spec](test/spec.js). ## Related projects - [linear-converter](https://github.com/javiercejudo/linear-converter): flexible linear converter with built in conversions for common units. - [linear-conversion](https://github.com/javiercejudo/linear-conversion): Linear conversion class for *linear-converter*. - [rescale](https://github.com/javiercejudo/rescale): rescales a point given two scales. - [rescale-util](https://github.com/javiercejudo/rescale-util): Rescale utilities. - [scale](https://github.com/javiercejudo/scale): scales normalised data. - [normalise](https://github.com/javiercejudo/normalise): normalise data to [0, 1]. --- _Source: https://npm.io/package/linear-arbitrary-precision · Machine-readable twin of the npm.io package page.
