Function Input Mode
Expressions and operations
“Expression” is a general term for standard formulas that join constants and variables with
operators (special symbols used in calculations) or simply indicate a value, variable, or function.
“Operation” refers to the execution of the operations included in an expression that consists
of operators or functions. Calculations include arithmetic operations and functions. Arithmetic
operations consist of the following operators and are performed in a prede ned order:
Arithmetic
operator
Description of calculation performed
Example
^
Exponent (power)
X^Y
-
Sign
-X
*, /
Multiplication, division
X*Y, X/Y
+, -
Addition, subtraction
X+Y, X-Y
“Function” refers to an operation performed on a speci ed value (function argument) to obtain
a result. (Not all functions require an argument.) Functions are expressed by words that are
determined by the speci c function performed, much like normal instructions (AREA, PERIOD,
etc.). The words used to denote instructions are known as control words and are treated, along with
functions, as special words.
Operations are subject to precedence. Operations are performed in the following order of
precedence:
1. Expressions enclosed in parentheses
2. Functions
3. ^
(exponents)
4. +, - (sign)
5. *, / (multiplication, division)
6. +, - (addition, subtraction)
Parentheses are used to change the order of operation precedence. Operators enclosed in
parentheses are executed before other operations. Expressions enclosed in parentheses are
evaluated in accordance with the order of precedence.
