Discounted Cash Flow Analysis: NPV and IRR The HP-12C provides functions for the two most widely-used methods of discounted cash flow analysis: NPV (net present value) and IRR (internal rate of return). These functions enable you to analyze financial problems involving cash flows (money paid out or recieved) occurring at regular intervals. As in compound interest calculations, the interval between cash flows can be any time period; however, the amounts of these cash flows need not be equal.

The Financial Registers In addition to the data storage registers discussed, the HP-12C has five special registers in which numbers are stored for financial calculations. These registers are designated n, i, PV, PMT, and FV. The first five keys on the top row of the calculator are used to store a number from the display into the corresponding register, to calculate the corresponding financial value and store the result into the corresponding register, or to display the number stored in the corresponding register.

Some calculator operations cannot be performed under certain conditions (for example, divide when X-register = 0). If you attempt such an operation under these conditions, the calculator will display the word Error followed by a digit, 0 through 8. Listed below are the definitions of each error number. 0 Mathematics error. When HP12c Platinum Calculator attempt to divide by zero. Also operations which would result in complex numbers (example: SQRT(-1)).

HP 12c (platinum) - Keyboard Functions ON Turns the calculator off and exits the program, retaining continuous memory. f Press to access gold functions. g Press to access blue functions. PREFIX Displays mantissa of number in the displayed X-register. ENTER Pushes number in display into the stack. CHS Changes sign of number or exponent of 10 in displayed X-register. EEX Enter exponent. After pressing, next numbers keyed in are exponents of 10.

Programming Basics Why Use Programs? A program is simply a sequence of keystrokes that is stored in the calculator. Whenever you have to calculate with the same sequence of keystrokes several times, you can save a great deal of time by incorporating these keystrokes in a program. Instead of pressing all the keys each time, you press just one key to start the program: the calculator does the rest automatically!
