Comparison Operators
Comparison operators are used in Boolean expressions (expressions which evaluate to either true or false) when we want to test things in our programs.
| Description | In Ruby |
|---|---|
| Equal to | == |
| Less than | < |
| Greater than | > |
| Not equal to | != |
| Less than or equal to | <= |
| Greater than or equal to | >= |
In addition to the comparison operators, the boolean operators, NOT, AND, OR can also be used in boolean expressions.
| ! (num < 30) | num is not less than 30 |
| num > 5 && num < 30 | num is greater than 5 and less than 30 |
| num < 5 || num > 30 | num is less than 5 or num is greater than 30 |
