special registers in which numbers are stored for financial calculations. These

the calculator are used to store a number from the display...

The exchange of money in a problem is depicted by vertical arrows. Money you 
receive is represented by an arrow pointing up from the point in the time line when 
the transaction occurs; money you pay out is represented by an arrow pointing 
down.

The form in which n is entered determines whether or not the calculator 
performs financial calculations in Odd-Period mode (as described on pages 
50 through 53). If n is a noninteger (that is, there is at least one nonzero 
digit to the right of the decimal point), calculations of i, PV, PMT, and FV are 
performed in Odd-Period...

The Payment Mode 
One more bit of information must be specified before you can solve a problem 
involving periodic payments. Such payments can be made either at the beginning 
of a compounding period (payments in advance, or annuities due) or at the end of 
the period (payments in arrears, or ordinary annuities). Calculations...

Compound Interest Calculations 
Specifying the Number of Compounding Periods and the Periodic 
Interest Rate 
Interest rates are usually quoted at the annual rate (also called the nominal rate): 
that is, the interest rate per year. However, in compound interest problems, the

If the answer calculated is not an integer (that is, there would be nonzero digits to 
the right of the decimal point), the calculator rounds the answer up to the next 
higher integer before storing it in the n register and displaying it.
*  For example, if 
n were calculated as 318.15, 319.00
 would be the displayed answer.   
n is...
