206  Function Key Index
 Sets payment 
mode to End for com-
pound interest calcula-
tions involving 
payments (page 39).
Ï Calculates simple 
interest (page 35).
w Stores or computes 
number of periods in 
financial problem (page 
34).
A Multiplies a number 
in displayed X-register 
by 12 and stores the 
resulting value in the 
n-register (page 41).
¼ Stores or computes 
interest rate per com-
pounding period (page 
34).
C Divides number in 
displayed X-register by 
12 and stores the result-
ing value in the i-register 
(page41).
$ Stores or computes 
the present value (that 
is, the initial cash flow) 
of a financial problem 
(page 34).
P Stores or computes 
payment amount (page 
34).
M Stores or computes 
future value (final cash 
flow) of a financial prob-
lem (page 34).
! Amortizes x num-
ber of periods using val-
ues stored in PMT, i, PV, 
and the display. 
Updates values in PV 
and n (page 54).
l Calculates the net 
present value of up to 
30 uneven cash flows 
and initial investment 
using values stored with 
J, K, and a 
(page 59).
L Calculates the 
internal rate of return 
(yield) for up to 30 
uneven cash flows and 
initial investment using 
values stored with J, 
K, and a (page 63). 
J Initial cash flow. 
Stores contents of dis-
played X-register in R
0
, 
initializes n to zero, sets 
N
0
 to 1. Used at the 
beginning of a dis-
counted cash flow prob-
lem (page 59).
K Cash flow j. Stores 
the contents of X-
register in R
j
, incre-
ments n by 1, and sets 
N
j
 to 1. Used for all cash 
flows except the initial 
cash flow in a dis-
counted cash flow prob-
lem (page 59).
V Calculates depreci-
ation using straight-line 
method. (page 68).
E Calculates bond 
price, given desired 
yield to maturity (page 
67).
S Calculates yield to 
maturity, given bond 
price (page 68).
a Stores the number 
(from 1 to 99) of times 
each cash flow occurs 
as N
j
. Assumes 1 unless 
otherwise specified 
(page 61).
Ý Calculates depreci-
ation using 
sum-of-the-years-digits 
method (page 68).
#Calculates deprecia-
tion using declining-bal-
ance method (page 68).
Statistics 
CLEAR² Clears statis-
tical storage registers 
R
1
 through R
6
 and stack 
registers (page 76).
_ Accumulates statis-
tics using numbers from 
X- and Y-registers in 
storage registers R
1
 
through R
6
 (page 76).
^ Cancels effect of 
numbers from X- and 
Y-registers in storage 
registers R
1
 through R
6
 
(page 77).
Ö Computes mean 
(average) of x-values 
and y-values using 
accumulated statistics 
(page 77).
h Computes weighted 
average of y-(item) and 
x-(weight) values using 
accumulated statistics 
(page 81).
v Computes sample 
standard deviations of x- 
and y-values using 
accumulated statistics 
(page 78).
