Variables
On a Casio calculator nine variables are available
A B C D E F X Y M
These variables are used to store data, constants, results and other values.
Example 1
To store the value 123 in variable A
SHIFT STO 1 2 3 RCL A 123→A
123.
Example 2
To recall the value 123 that was stored in variable A
STO RCL A A=
123.
Example 3
To store the value 5.2 in variable B
SHIFT STO 5 · 2 RCL B 5.2→B
5.2
Example 4
To convert rectangular coordinates (1, √3) to polar coordinates (r, θ)
Pol( 1 ٬ √ 3 ) = Pol(1,√3)
2.
and show the value of r = 2 from variable E
RCL E E=
2.
and show the value of θ = 1.047197551 from variable F
RCL F F=
1.047197551
Example 5
To add the value 123 to variable M
M 1 2 3 123_
0.M+ 123M+
123.
When this independant memory contains data, it is shown in the status line by an M.
