Recital Operators

Assignment Operators

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

String Search Operator

String Substitution Operator

Execution Operator

Concatenation of Strings and Other Data Types
