No calculation is done. Calculates 5 − 1. Calculates 8 . (5 − 1) Storage Registers Numbers (data) in the hp 12c platinum are stored in memories called "storage registers" or simply "registers." (The singular term " memory" is sometimes used in this handbook to refer to the entire collection of storage registers.) Four special registers are used for storing numbers during calculations (these "stack registers" are described in Appendix A), and another (called the "LAST X" register) is used for storing the number last in the display before an operation is performed in RPN mode. In addition to these registers into which numbers are stored automatically, up to 20 "data storage" registers are available for manual storage of numbers. These data storage registers are designated R0 through R9 and R.0 through R.9. Still other storage registers - referred to as the "financial registers" - are reserved for numbers used in financial calculations. Storing and Recalling Numbers To store the number from the display into a data storage register: 1. Press ? (store). 2. Key in the register number: 0 through 9 for registers R0 through R9, or .0 through .9 for registers R.0 through R.9. Similarly, to recall a number from a storage register into the display, press : (recall), then key in the register number. This copies the number from the storage register into the display; the number remains unaltered in the storage register. Furthermore, when this is done, the number previously in the display is automatically held inside the calculator for a subsequent calculation, just as the number in the display is held when you key in another number.
