If you do so, however, you will need to press M twice in the next step for the reason discussed in the first footnote on page 32; you would not have to press M twice if you had not pressed 12 z after w in the example above. We choose to show this and the following example in a parallel format so that the procedure is easy to remember: the number you key is the number of the final payment — either the fractional payment or the balloon payment — whose amount is to be calculated.

Stores PV with minus sign for cash paid out. Stores PMT with minus sign for cash paid out. You can calculate this final, fractional, 58th deposit as in Example 1, except that for this example you must subtract the original FV. In Example 1, the original FV was zero. The procedure is as follows:. Enter the number of payments or periods, using n or A.

If we. Remember that it is not necessary to store the number of payments in n before calculating the amount of the final, fractional payment. Refer to the preceding footnote. However, this balance would not include the interest accrued during the 58th month.

Enter either or both of the following:. Assume the purchase date is one month prior to the date of the first payment. Note: Remember to observe the cash flow sign convention. Press P to calculate the payment amount. Calculate how much these deposits should be. Press M to calculate the future value. If the seller requests a balloon payment at the end of 5 years, what would be the amount of the balloon? The cash flow diagrams and examples presented so far have dealt with financial transactions in which interest begins to accrue at the beginning of the first regular payment period.

However, interest often begins to accrue prior to the beginning of the first regular payment period. Note that the odd period is always assumed by the calculator to occur before the first full payment period. The following two cash flow diagrams represent transactions including an odd period for payments in advance Begin and for payments in arrears End.

Clearing Storage Registers To clear a single storage register — that is, to replace the number in it with zero — merely store zero into it.

Storage Register Arithmetic Suppose you wanted to perform an arithmetic operation with the number in the display and the number in a storage register, then store the result back into the same register without altering the number in the display. The hp 12c enables you to do all this in a single operation: 1. Section 1: Getting Started 25 Storage register arithmetic is possible with only registers R 0 through R 4. Keystrokes Display Note that the display continues to show the amount subtracted; the answer is placed only in R 0.

Section 2: Percentage and Calendar Functions 27 Net Amount A net amount — that is, the base amount plus or minus the percentage amount — can be calculated easily with your hp 12c, since the calculator holds the base amount inside after you calculate a percentage amount.

Keys in the base amount and separates it from the percentage. Amount of discount. Base amount less discount. Total cost: base amount less discount plus tax. To find the percent difference between two numbers: 1. Key in the base number. Key in the other number. Section 2: Percentage and Calendar Functions 29 To find what percentage a number is of a total, when you already know the total number: 1.

Key in the total number. Keystrokes 7. Display 7. Date Format For each of the calendar functions — and also for bond calculations E and S — the calculator uses one of two date formats. To key in a date with this format in effect: 1. Dates are displayed in the same format. For example, to key in April 7, Keystrokes Display 4. Stores the annual interest rate. Stores the principal. Accrued interest, day basis. Total amount: principal plus accrued interest.

All information in Continuous Memory is preserved even while the calculator is turned off. Furthermore, information in Continuous Memory is preserved for a short time when the batteries are removed, so that you can change the batteries without losing your data and programs. When only two decimal places are displayed, numbers are rounded to two decimal places: if the third digit is 5 through 9, the second digit is increased by one; Page Scientific Notation Display Format The standard display format, plus the specified number of decimal places, remain in effect until you change them; they are not reset each time the calculator is turned on.

However, if Continuous Memory is reset, when the calculator is next turned on numbers will be displayed in the standard display format with two decimal places shown.

Third entry. Page Standard Deviation Example: To calculate the standard deviations of the x-values and of the y-values from the preceding example: Keystrokes The formulas used in the hp 12c for calculating s population standard deviation based on a sample of the population.

Thus, current statistical convention calls them sample standard deviations. So we have assumed that the seven salespersons are a sample of the population of all salespersons, and our formulas derive best estimates of the population from the sample. Press 0gR to compute the y-intercept A.

These functions are useful for specialized financial calculations as well as for general mathematics calculations. One-Number Functions Most of the mathematics functions require that only one number be in the calculator that is, the number in the display before the function key is pressed. Page Section 7: Mathematics And Number-Alteration Functions — that is, it replaces all digits to the left of the decimal point by 0.

The original number can be recalled to the display by pressing gF. Page The Power Function 4. Press q to calculate the power. Like the arithmetic Display 2. 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.

Press fs to set the calculator back to Run mode. If the calculator is already in Run mode that is, the PRGM status indicator in the display is not lit , skip this step. Page Program Memory At the left of the display is the number of the program line within program memory. The remaining digits in the display comprise a code that indicates what instruction has been stored in that program line.

The first digit in the keycode is the number of the key row, counting from row 1 at the top; Page The 00 Instruction And Program Line 00 08 after executing the seven instructions you keyed in. Page Expanding Program Memory The instruction you key in is stored in program line 09, and the instruction i00 is automatically stored in program lines 10 through Pausing During Program Execution When a running program executes a u instruction, program execution halts for about 1 second, then resumes.

Do not key in the quantity and cost of each item; these numbers will vary each time the program is run. Page Sets calculator to Run mode. Clears registers R — R Stores tax rate.

Enters quantity and price of first item on invoice. Page Stopping Program Execution Example: Replace the program above by one containing t instructions instead of u instructions.

Clears program memory. Page 5, Either of these conditions signifies that the program itself probably contains an error. Page Branching And Looping Backward branching is typically done to create loops as described next ; forward branching is typically done in conjunction with an o or m instruction for conditional branching as described afterward.

Clears program memory Stores the number from the display into register R. Page 30gA This program line is the one to which program execution will later branch. Page — This is the beginning of the first pass through the loop. Line f!. Page Conditional Branching The hp 12c provides two conditional test instructions that are used in programs for conditional branching: o tests whether the number in the X-register represented by the x in the key symbol is less than or equal to the number in the Y-register represented by the y in the key symbol.

Page Y-registers when instructions such as o are executed, it is extremely helpful when writing the program to show the quantities in each register after each instruction is executed, as in the following diagram. Page 20,, rather than the income, would be in the Y-register when the b instruction in line 08 is executed. Branches to program line Income has been placed in X-register and test value has been placed in Y-register.

Line go. Condition tested by o was false, Page Program Editing To change a single instruction in program memory: 1. Press fs to set the calculator to Program mode. Example: With the last program from the preceding section stored in the calculator, suppose you wanted to add a - instruction at the end in order to calculate the net income after taxes. You could do so as follows Press gi.

This sets the calculator to the proper program line for adding the new instruction s in the next step. Page Adding Instructions By Branching — usually, the last program line to be executed before the added instruction s.

This sets the calculator to the proper program line for inserting a i instruction in the next step. This i instruction will replace whatever Page Keystrokes gi. Sets calculator to program line Page 12, Keys in instruction immediately following point at which new instructions are being added.

Page Multiple Programs You can run programs after the first one stored in program memory by setting the calculator to the first line of the program using i before pressing t. Keystrokes gi. Press fs to set the calculator to Run mode. If the calculator is already in Run mode, skip this step. Press gi followed by two digits that specify the first line of the program.
