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(Decimal.parse('0.2') + Decimal.parse('0.1')); // displays 0.3

Usage

To use this library in your code :

• add a dependency in your pubspec.yaml :

dependencies:
  decimal: ^0.3.0

• add import in your dart code :

import 'package:decimal/decimal.dart';

• Start computing using Decimal.parse('1.23').

Hint : To make your code shorter you can define a shortcut for Decimal.parse :

final d = Decimal.parse;
d('0.2') + d('0.1'); // => 0.3
