decimal 1.0.0-nullsafety

The decimal package allows you to deal with decimal numbers without loosing precision.

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
