Operator | Syntax | Description |
multiply, divide | i * j / k | Arithmetic operators for numeric types only. |
percent | i % j | Calculates i as a percent of j; numeric types only. |
add, subtract | i + j - k | Arithmetic operators for numeric types only. |
equal | i == j | Comparison operators for string, numeric, and date types. |
not equal | i != j | |
less than | i < j | Comparison operators for numeric and date types only. |
less than or equal | i <= j | |
greater than | i > j | |
greater than or equal | i >= j | |
IN set | i IN ('apples','oranges') | Sets can be of any type. |
IN range | i IN (j:k) | Ranges must be numeric or date types. |
NOT | NOT( i ) | Boolean operators. Parentheses are required for NOT. |
AND | i AND j AND k | |
OR | i OR j OR k | |
parentheses | () | Used for grouping. |
DomEL also defines the following operations as functions.
Function | Syntax | Description |
startsWith | startsWith(i, 'prefix') | Comparison operators for strings. |
endsWith | endsWith(j, 'suffix') | |
