Decimal to Hexadecimal

I just got my HP 49G and am trying to convert a decimal number to
hexadecimal. How would I go about doing this on the calculator?

The manual does not really give much direction.

Thanks,
Rob Kantor

- enter your number like this:
#xxxxy
where xxxx is your number, and y is a lowercase letter indicating the
base of the number (d for decimal, h for hexadecimal, b for binary, o
for octal)
- change the current base: HEX, DEC, OCT, BIN
- look at the result on the stack

Note that you can omit the 'y' in your number if it designated the same
base as the current one.

Incidentally, there's surely a better program on www.hpcalc.org, I
remember having trying one for my HP48, which saved the current base, and
displayed my entered number in all the 4 possible bases on the screen.

I'm not so sure... ;)

Hi Rob!

First set hex mode by pressing HEX. You can get the command HEX for
example by pressing the keys [blue-shift], [CONVERT] (key 6), [F2],
[F1]. When HEX mode is on all binary integers are displayed in
hexadecimal. Now enter your number and then press R->B. You access the
command R->B by pressing the keys [blue-shift], [CONVERT] (key 6),
[F2], [F5].

Greetings,
Nick.

You mean probably the tool BACO (Base Conversion). It is slightly
obsolate on hpcalc.org since at the time it was written the powerful
display tools of ROM 19-6 were not yet available. Hence, load the
updated version of BACO from

ftp://ftp.math.fu-berlin.de/pub/usr/raut/HP49/tools/

It immediately displays a user binary in all modes HEX, DEC, OCT,
BIN in one screen. The base of the input binary can be specified.
All digits are shown even if the number of its binary digits is 64,
the maximum number for a user binary. User binaries are special
hexastrings. A system hexastring can be arbitrarily long ...
