Arithmetic Operators
Recital supports the use of the following Arithmetic Operators:
Operator | Operation | Precedence |
---|---|---|
() | Parentheses | 1 |
** | Exponentiation | 2 |
* | Multiplication | 3 |
/ | Division | 3 |
% | Modulus/Remainder | 3 |
+ | Addition | 4 |
- | Subtraction | 4 |
When dealing with Date data types, the operators have the following definitions:
Operator | Operation |
---|---|
+ | <expD> + <expN> returns a date plus the number of days specified in <expN>. |
- | Returns the interval between the two dates as a number of days. |
Example
? 2*3^2 18 ? 2*25%7 1.00 ? date() + 30 - date() 30
Comparison Operators
Increment and Decrement Operators
String Concatenation Operator
When dealing with string data types, the + and - operators perform the following concatenation operations:
Operator | Operation |
---|---|
+ | Concatenate the right hand string to the end of the left hand string. |
- | Concatenate the right hand string to the end of the left hand string after trimming the left hand string of trailing spaces. |
Example
? [Hello] + [ ] + [ World] Hello World ? [Hello ] - [ World] Hello World
