Windward Equations Operators Reference
Here is the complete list of Windward equation operators.
Valid operands for these operators are:
- numbers
- Boolean values
- variable references (e.g. "${VariableName}") whose values are numbers or Boolean values
- Windward functions that return a number or Boolean value
- other equations that return a number or Boolean value
When an equation is evaluated, the value of a variable is substituted for its reference.
The logical operators expecting a Boolean value treat NULL as false.
| Operator | Description |
|---|---|
| ( | Open parenthesis |
| ) | Close parenthesis |
| , | Comma |
| * | Multiplication |
| / | Division |
| div | Division |
| % | Modulus - divide the left-hand operand by the right-hand operand and return the remainder |
| mod | Modulus - divide the left-hand operand by the right-hand operand and return the remainder |
| + | Addition |
| - | Subtraction |
| = | Assignment |
| == | Comparison - if the two operands are equal return true; else return false |
| eq | Equal |
| != | Not equal - return true if the operands are not equal; else return false |
| ne | Not equal - return true if the operands are not equal; else return false |
| < | Less than - return true if the left-hand operand is less than the right-hand operand; else return false |
| lt | Less than - return true if the left-hand operand is less than the right-hand operand; else return false |
| > | Greater than - return true if the left-hand operand is greater than the right-hand operand; else return false |
| gt | Greater than - return true if the left-hand operand is greater than the right-hand operand; else return false |
| <= | Less than or equal to - return true if the left-hand operand is less than or equal to the right-hand operand; else return false |
| le | Less than or equal to - return true if the left-hand operand is less than or equal to the right-hand operand; else return false |
| >= | Greater than or equal to - return true if the left-hand operand is greater than or equal to the right-hand operand; else return false |
| ge | Greater than or equal to - return true if the left-hand operand is greater than or equal to the right-hand operand; else return false |
| && | Logical AND - return true if both operands are true, else return false |
| and | Logical AND - return true if both operands are true, else return false |
| || | Logical OR - return true if either or both operands are true, else return false |
| or | Logical OR - return true if either or both operands are true, else return false |
| ! | Logical NOT - return true if the operand is false; else return false |
| not | Logical NOT - return true if the operand is false; else return false |
