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.

? 2*3^2
        18
? 2*25%7
      1.00
? [Hello     ] - [ World]
Hello World
? date() + 30 - date()
        30
