# Comparison

Equality operator (`==`) returns `true` when both operands are in the same currency and have an equal amount.

```dart
import 'package:money2/money2.dart';
fiveDollars == fiveDollars;  // => true
fiveDollars == sevenDollars; // => false
fiveDollars == fiveEuros;    // => false (different currencies)
```

Money values can be compared with the `<`, `<=`, `>`, `>=` operators, or the method `compareTo()` from the interface `Comparable<Money>`.

**These operators and method `compareTo()` can be used only between money values in the same currency. Runtime error will be thrown on any attempt to compare values in different currencies.**

```dart
import 'package:money2/money2.dart';
fiveDollars < sevenDollars; // => true
fiveDollars > sevenDollars; // => false
fiveEuros < fiveDollars;    // throws ArgumentError!
```
