Function Summary and Index
‛ Enter exponent;
next digits keyed in are
exponents of 10
(page 19).
0 through 9 digit
keys (page 22).
. Decimal point
(page 22)

Display Control

• Selects fixed
point display mode
(page 58).
i Selects scientific
notation display mode
(page 59).
^ Selects
engineering notation
display mode (page
59).
Mantissa. Pressing
´ CLEAR u
displays all 10 digits of
the number in the X-
register as long as the
u key is held
down (page 60). It also
clears any partial key
sequences
(page 19).
Hyperbolic
Functions
P[
P\
P] Compute
hyperbolic sine,
hyperbolic cosine, or
hyperbolic tangent,
respectively (page 28).
H [, H
\, H ]
Compute inverse
hyperbolic sine, inverse
hyperbolic cosine, or
inverse hyperbolic
tangent, respectively
(page 28).
Index Register
Control
V Index register (R
Storage register for:
indirect program
execution – branching
with t and G,
looping with I and
s – indirect flag
control, and indirect
display format control
(page 107). Also used
to enter complex
numbers and activate
Complex mode (page
121).
% Indirect
operations. Used to
address another storage
register through R
purposes of storage,
recall, storage,
arithmetic, and program
loop control (page
107). Also used with
m to allocate
storage registers (page
215).
Logarithmic and
Exponential
Functions
N Computes natural
logarithm (page 28).
' Natural
antilogarithm. Raises e
to power of number in
display (X-register)
).
I
(page 28).
o Computes
common logarithm
(base 10) (page 28).
@ Common
antilogarithm. Raises
10 to power of number
in display (X-register)
(page 28).
Y Raises number in
Y-register to power of
for
I
