We'll need to test how one scalar compares with another. Just like in algebra, perl can compare numbers and just like in a dictionary, perl can compare strings. The result of the comparison is either true or false.
| Comparison | Numeric | String |
| Equal | == | eq |
| Not Equal | != | ne |
| Less Than | < | lt |
| Greater Than | > | gt |
| Less Than or Equal To | <= | le |
| Greater Than or Equal To | >= | ge |
