Decimal/Octal Conversions
|
|
|
|
The OCT (decimal to octal) and
DEC (octal to decimal) functions allow
you to convert numbers that are in the X-register to their decimal or octal
equivalents. For example, to convert the octal number 326 to its decimal
equivalent.
|
|
|
|
|
|
|
|
To convert the decimal number 8962 to its octal equivalent:
|
|
|
|
|
|
|
|
If you attempt to use OCT when x is noninteger or the
absolute value of x is greater than 1,073,741,823 (decimal), the display will
show DATA ERROR. If you attempt
to use DEC when x is noninteger or the number to be
converted contains an 8 or 9, the display will show
DATA ERROR. The largest octal
number that can be converted is 7,777,777,777.

Exchanging X and Any Register
|
|
|
|
Earlier
in this handbook you learned how
X Y exchanges the contents of the
X-register with the contents of the Y-register. Using
X<> you can exchange the contents of X with
the contents of any storage register, including the rest of the stack (T, Z, and
Y), and LAST X.
|
|
|
|
To exchange X with another stack register or LAST X, execute
X<> , press
· (decimal point) to specify
the desired register (T, Z, Y, X, or L for LAST X).
|
|
|
|
To exchange X with any numbered register form 00 through 99, simply execute
X<> and supply the two-digit register address.

Paper Advance
|
|
|
|
This special function, ADV , is used in the
HP-41C when you have the optional printer plugged into an input/output port on
the HP-41C.
|
|
|
|
ADV causes the printer paper to advance one line, if
the printer is plugged into the HP-41C. In the absence of a printer,
ADV does noting. Please consult the owner’s
handbook included with the printer for additional functions and
information.
