Numeric Expressions

A numeric expression is a combination of numeric elements (such as numbers, variables, and functions) and operators that evaluates to a numeric value.

An expression can contain any of the following in any combination:

Arrays	Mathematical operators
Attributes	Name-Index numbers
Boolean operators	Numbers
Distributions	Subroutines
Macros	System functions
Math function table functions	Variables

The following mathematical operators are available:

Operator	Meaning	Example
+	Addition	A=B+C
-	Subtraction	A=B-C
*	Multiplication	A=B*C
/	Division	A=B/C
Mod or @	Modulus	A=B Mod C (assigns the remainder of B divided by C to A)
**	Exponentiation	A=B**C (assigns the value of B raised to the C power)

You can perform additional mathematical operations using math functions. For more information on operator precedence rules and expression nesting, see Operator Precedence.

Please Note: In each of the examples above, if A is an integer number and B and C are both real numbers, the result will be truncated unless ROUND() is used (e.g., A = ROUND(B+C)).
