下表说明了比较运算符的说明和符号：
表 11-4 比较运算符
| 说明 | 符号 |
|---|---|
| 相等 | = |
| 不相等 | <> |
| 小于 | < |
| 大于 | > |
| 小于或等于 | <= |
| 大于或等于 | >= |
以下示例说明了比较运算符的用法：
示例 1：
Dim A, B, IsNotEqual A = 10 B = 20 IsNotEqual = (A <> B) ' Inequality: A <> B 'IsNotEqual: A does not equal B: True
示例 2：
Dim A, B, IsLessThan A = 10 B = 20 IsLessThan = (A < B) ' Less than: A < B 'IsLessThan: A is less than B: True
示例 3：
Dim A, B, IsGreaterThan A = 20 B = 10 IsGreaterThan = (A > B) ' Greater than: A > B 'IsGreaterThan: A is greater than B: True
示例 4：
Dim A, B, IsLessThanOrEqual A = 10 B = 10 IsLessThanOrEqual = (A <= B) ' Less than or equal to: A <= B 'IsLessThanOrEqual: A is less than or equal to B: True
