HP 12C Calculator - Removing the "C" from the Display
A capital C appears near the lower right corner of the HP 12C calculator display.
Pressing [STO][EEX] will remove the C from the display.
The C status indicator is used in Odd-Period calculations. When interest on a cash flow begins to accrue before the beginning of the first regular payment period, it is necessary to place the HP 12C calculator in Odd-Period mode. This is done by entering a non-integer value for n. The integer portion represents the number of full periods. The fractional part specifies the length of the odd period as a fraction of the full period. The calculations during the odd period can be done with either simple or compound interest. If the C status indicator in the display is not lit, simple interest is used. Compound interest, indicated by the C in the display, is set by pressing [STO][EEX]. Pressing [STO][EEX] again returns the calculations to simple interest for the odd period.
