运算符是一个符号，告诉编译器执行特定的数学或逻辑操作。
Rexx具有各种类型的运算符，下面还将对其进行详细说明-
Rexx语言支持普通的算术运算符，就像任何一种语言一样。以下是Rexx中可用的算术运算符。
| Operator | Description | Example |
|---|---|---|
| + | Addition of two operands | 1 + 2 will give 3 |
| − | Subtracts second operand from the first | 1 – 2 will give -1 |
| ∗ | Multiplication of both operands | 2 ∗ 2 will give 4 |
| / | Division of numerator by denominator | 2 / 2 will give 1 |
| // | Remainder of dividing the first number by the second | 3 // 2 will give 1 |
| % | The div component will perform the division and return the integer component. | 3 % 2 will give 1 |
关系运算符允许对象的比较。以下是Rexx中可用的关系运算符。在Rexx中，真值用1表示，假值用0表示。
| Operator | Description | Example |
|---|---|---|
| == | Tests the equality between two objects | 2 = 2 will give 1 |
| < | Checks to see if the left object is less than the right operand. | 2 < 3 will give 1 |
| =< | Checks to see if the left object is less than or equal to the right operand. | 2 =< 3 will give 1 |
| > | Checks to see if the left object is greater than the right operand. | 3 > 2 will give 1 |
| >= | Checks to see if the left object is greater than or equal to the right operand. | 3 > 2 will give 1 |
逻辑运算符用于评估布尔表达式。以下是Rexx中可用的逻辑运算符。
| Operator | Description | Example |
|---|---|---|
| & | This is the logical “and” operator | 1 or 1 will give 1 |
| | | This is the logical “or” operator | 1 or 0 will give 1 |
| \ | This is the logical “not” operator | \0 will give 1 |
| && | This is the logical exclusive “or” operator | 1 && 0 will give 1 |
Groovy提供了四个按位运算运算符。下面是Groovy中可用的按位运算运算符。
| Sr.No. | Operator & Description |
|---|---|
| 1 |
bitand This is the bitwise “and” operator |
| 2 |
bitor This is the bitwise “or” operator |
| 3 |
bitxor This is the bitwise “xor” or Exclusive or operator |
下表按优先级从高到低的顺序显示了Rexx运算符优先级。
| Operators | Precedence |
|---|---|
| Prefix operators | + – \ |
| Addition and subtraction | + – |
| Comparison operators | = == > < >= <= |
| Logical AND | & |
| Logical OR | | |
| EXCLUSIVE OR | && |
