3.8.1 Defining expressions
An expression may consist of one or more operations. Each one of them may be defined
by any valid combination of variables, constants, functions and operations. Press [ENTER]
To accept the expression entered and calculate the value.
Quick parenthesis insertion
To place a portion of an expression between parenthesis, select the portion and press one
of the parenthesis keys "(" or ")". If while a portion of the expression is selected, an operation
key is pressed, the selection will appear between parenthesis and it will be preceded by the
operation just defined.
Example: Having the expression "1+1/X+1/(X+1)+1". When selecting the "1/(X+1)+1"
portion and pressing the "SIN" option, the expression will become
"1+1/X+Sin(1/(X+1)+1)".
Variables for the calculator
The calculator offers up to 26 variables (from "A" to "Z", except "Ñ",) may be used to store
numeric values and use them later.
Assigning a value to a variable: A = 34.234
Reference to a variable: Sin(A/2)
A single expression may contain both assignment and reference operations. Use the ":"
character as separator.
A=34.234:Sin(A/2) is the same as Sin((A=34.234)/2)
Constants
The following constants are available and they may be accessed from the softkey menu.
Various operations
In the following examples, the "x" and "y" values indicate any valid combination of constants,
variables or expressions.
Arithmetic operations.
The values of the calculator variables "A" - "Z" are independent from the values of local parameters
"A" - "Z" (also called P0 through P25).
i
PI Value of pi (3.14159...)
MM -> INCHES mm/inch conversion factor.
INCHES ->MM inch/mm conversion factor.
x + y Add
x - y Subtract
x *y Multiply
x / y Divide
x % y Percentage 10%50 = 5
x ^ y Power 2^3 = 2  2  2 = 8
x! Factor 3! = 3  2  1 = 6
