The Recital/4GL supports the use of the following Mathematical Operators:
| Operator | Operation | Precedence | Data Types |
|---|---|---|---|
| () | Parentheses | 1 | N,C,D |
| ** | Exponentiation | 2 | N |
| * | Multiplication | 3 | N |
| / | Division | 3 | N |
| % | Modulus/Remainder | 3 | N |
| + | Addition | 4 | N,C,D |
| - | Subtraction | 4 | N,C,D |
When dealing with Character data types, the operators have the following definitions:
| 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. |
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 ? [Hello ] - [ World] Hello World ? date() + 30 - date() 30
