Name Keys to press in modes Remarks
24h
 … 
\

Sets 24h time display mode meaning 1:23 AM
becomes 1:23, and 1:45 PM becomes 13:45.
2COMPL
 … 
\

Sets 2‘s complement mode like in
HP-16C .
2
x

x

\

A - C
ABS

\

Returns the absolute value.
 
DECM
Returns
2 2
y x r
 
in X and clears Y .
ACOS
  
DECM
Returns
 
x arccos
.
ACOSH
    
DECM
Inverse hyperbolic cosine, known as arcosh .
Note there is no need for pressing

here.
AGM
 … 
DECM
Returns the arithmetic-geometric mean of x and
y
.
ALL

n

\

ALL 00 works like ALL in HP-42S . For
x
> 10
13
,
however, display will switch to SCI or ENG with
the maximum number of digits necessary (see
SCIOVR / ENGOVR). The same will happen if
and more than 12 digits are required
to show
x
completely.
AND

Integer Works bitwise as in HP-16C .
DECM
Works like AND in HP-28S , i.e. x and y are in-
terpreted before executing this operation. 0 is
―false‖, any other real number is ―true‖.
ANGLE
 … 
DECM
Returns the angle between positive x-axis and
the straight line from the origin to the point
(
x, y
) , i.e. . This is a two-number
function, it consumes
y
.
ASIN
  
DECM
Returns
 
x arcsin
.
ASINH
    
DECM Inverse hyperbolic sine, known as arsinh .
ASR

ASR n

Integer
Works like n (up to 63) consecutive ASR com-
mands in HP-16C, c orresponding to a division
by 2
n
. ASR 0 executes as NOP, but loads
L
.
ATAN
  
DECM Returns
 
x arctan
.
ATANH
    
DECM Inverse hyperbolic tangent, known as artanh .
