1.2.2 Using Arithmetic Operators and Functions

Six standard arithmetic operators are available for use in $repeat and $macro commands. The following table lists these operators and their order of precedence, from highest to lowest.

Table 1-3. Arithmetic Operators
Operator	Examples	Description	Precedence
**	2**3	Exponentiation	1
*	2*I	Multiplication	2
/	4/2	Division	2
%	9%8	Modulus	2
+	2+4	Addition	3
-	4-I	Subtraction	3

One arithmetic function is available for use in arithmetic expressions used in $repeat and $macro commands. The following table shows the arithmetic function and its bases.

Table 1-4. Arithmetic Function and Bases
Function	Base
LOG2	Binary
LOG8	Octal
LOG16	Hexadecimal
LOG	Decimal

The LOG function returns an integer value. For example:


	`LOG2(32)= 5 <==> 25 = 32` `LOG2(33)= ceil(5.0444) = 6 <==> 26 = 64`

Ceil(x) returns the smallest integer that is not less than x.
