Rexx - Operators
An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations.
Rexx has various types of operators which are also explained in detail as follows −
- Arithmetic operators
- Relational operators
- Logical operators
- Bitwise operators
Arithmetic Operators
The Rexx language supports the normal Arithmetic Operators as any the language. Following are the Arithmetic Operators available in Rexx.
| 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 |
Relational Operators
Relational Operators allow of the comparison of objects. Following are the relational operators available in Rexx. In Rexx the true value is denoted by 1 and the false value is denoted by 0.
| 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 |
Logical Operators
Logical Operators are used to evaluate Boolean expressions. Following are the logical operators available in Rexx.
| 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 |
Bitwise Operators
Groovy provides four bitwise operators. Below are the bitwise operators available in Groovy.
| 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 |
Operator Precedence
The following table shows the Operator Precedence for the Rexx operators in order of descending priority of their precedence.
| Operators | Precedence |
|---|---|
| Prefix operators | + - \ |
| Addition and subtraction | + - |
| Comparison operators | = == > < >= <= |
| Logical AND | & |
| Logical OR | | |
| EXCLUSIVE OR | && |
