Calculating with Numeric Variables

Using Arithmetic Operators in Assignment Statements

One way to perform calculations on numeric variables is to write an assignment statement using arithmetic operators. Arithmetic operators indicate addition, subtraction, multiplication, division, and exponentiation (raising to a power). For more information about arithmetic expressions, see the discussion in SAS Language Reference: Concepts.

The following table shows operators that you can use in arithmetic expressions.

Table 8.1 Operators in Arithmetic Expressions

Operation	Symbol	Example
addition	+	x = y + z;
subtraction	–	x = y - z;
multiplication	*	x = y * z
division	/	x = y / z
exponentiation ...
