Dart Decimals

This project enable to make computations on decimal numbers without loosing precision like double operations.

For instance :

// with double
print(0.2 + 0.1); // displays 0.30000000000000004

// with decimal
print(dec('0.2') + dec('0.1')); // displays 0.3

Usage

To use this library in your code : * add a dependency in your pubspec.yaml :

dependencies:
  decimal: '<1.0.0'
  • add import in your dart code :
import 'package:decimal/decimal.dart';
  • Start computing using dec('1.23').

Limitation

WARNING : If you are using this package through dart2js, results may not be good. This is because dart2js does not implement yet integers with arbitrary precision. Once issue 1533 fixed, you should be able to use it in javascript.
