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.
Show Example
| 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.
Show Example
| 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.
Show Example
| 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.
Show Example
| 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.
