Expr Language - Operations
Expr provides basic arithmetic operations, comparisons, text operations and logical operations.
| Operations | Comments |
|---|---|
+ - * / | Basic operators. When used, the value is converted to a number. Follows the general precedence rules for arithmetic, so (2 + 3 * 4 = 14). |
= != | Equality and non-equality: if either part of the comparison is a number, the other part is also converted into a number. If both values are texts, then text comparison is used. Text comparison ignores leading and trailing whitespace and is case-insensitive (according to Jira's system locale). |
< <= > >= | Numerical comparisons. When used, both values are converted to numbers. |
AND, OR, NOT | Logical operations. |
CONCAT | An operation that joins together two text strings. Works similar to the function of the same name: a CONCAT b is the same as CONCAT(a, b). |
( ) | Parentheses can be used to group the results of operations prior to passing them to other operations. |
Order of Operations
When several types of operations are used, they are done in the following order:
- Arithmetic operations
- Text operations (CONCAT)
- Comparison operations
- Logical operations.
