Memory Registers

iCALCULA offers a mechanism to store and perform arithmetic operations with data out of the stack. A list of 20 non volatile registers is kept along with the four values in the stack. Data can be moved or operated into these registers out from the stack and reciprocally.

|CLEAR ALL| : Clears all registers

|CLEAR| : Enters the list of registers to select which one will be cleared

|STO+| : Enters the list of registers. Selected register will be updated to the value (selected register + x-register)

|STO−| : Enters the list of registers. Selected register will be updated to the value (selected register - x-register)

|STO×| : Enters the list of registers. Selected register will be updated to the value (selected register × x-register)

|STO÷| : Enters the list of registers. Selected register will be updated to the value (selected register ÷ x-register)

|RCL| : Enters the list of registers. x-register will be updated to the value of the selected register

|RCL+| : Enters the list of registers. x-register will be updated to the value (x-register + selected register)

|RCL−| : Enters the list of registers. x-register will be updated to the value (x-register - selected register)

|RCL×| : Enters the list of registers. x-register will be updated to the value (x-register × selected register)

|RCL÷| : Enters the list of registers. x-register will be updated to the value (x-register ÷ selected register)
