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
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
