u Variables (Alpha Memory)
This calculator comes with 28 variables as standard. You can use variables to store values
you want to use inside of calculations. Variables are identified by single-letter names, which
are made up of the 26 letters of the alphabet, plus
r and θ . The maximum size of values that
you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent.
• Variable contents are retained even when you turn power off.
u To assign a value to a variable
[value] a [variable name] w
Example 1 To assign 123 to variable A
Abcdaav(A) w
Example 2 To add 456 to variable A and store the result in variable B
Aav(A) +efga
al(B) w
u To assign the same value to more than one variable
[value] a [first variable name] a3(~) [last variable name] w
• You cannot use “
r ” or “ θ ” as a variable name.
Example To assign a value of 10 to variables A through F
Abaaav(A)
a3(~)at(F)w
u String Memory
You can store up to 20 strings (named Str 1 to Str 20) in string memory. Stored strings can be
output to the display or used inside functions and commands that support the use of strings as
arguments.
For details about string operations, see “Strings” (page 8-18).
Example To assign string “ABC” to Str 1 and then output Str 1 to the display
A!a(
