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
The Rexx language supports the normal Arithmetic Operators as any the language. Following are the Arithmetic Operators available in Rexx.
|+||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 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.
|==||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 are used to evaluate Boolean expressions. Following are the logical operators available in Rexx.
|&||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 provides four bitwise operators. Below are the bitwise operators available in Groovy
|bitand||This is the bitwise “and” operator|
|bitor||This is the bitwise “or” operator|
|bitxor||This is the bitwise “xor” or Exclusive or operator|
The following table shows the Operator Precedence for the Rexx operators in order of descending priority of their precedence.
|Prefix operators||+ - \|
|Addition and subtraction||+ -|
|Comparison operators||= == > < >= <=|
