| Chris@0 | 43 * greaterThanOrEqualTo($v1, $v2) |
| Chris@0 | 44 * lessThan($v1, $v2) |
| Chris@0 | 45 * lessThanOrEqualTo($v1, $v2) |
| Chris@0 | 46 * equalTo($v1, $v2) |
| Chris@0 | 47 * notEqualTo($v1, $v2) |
| Chris@0 | 48 |

| Chris@0 | 50 |
| Chris@0 | 51 ```php |
| Chris@0 | 52 use Composer\Semver\Comparator; |
| Chris@0 | 53 |
| Chris@0 | 54 Comparator::greaterThan('1.25.0', '1.24.0'); // 1.25.0 > 1.24.0 |
