HP-15C Mini-quiz: My original solutions Message #10 Posted by Valentin Albillo on 17 Oct 2006, 5:46 a.m., in response to message #9 by Paul Dale
Certainly, certainly ! ...
I've been out and about and just completely forgot about this simple mini-quiz which, as stated, I concocted on the fly to try and cheer up the forum at a time where new postings were really scarce.
The forum's been much livelier since then, and I've been too busy so I simply forgot about it, sorry. Anyway, here you are, my original solutions:
-0.1416 assume 42 is in X, can't use Pi 3 steps
STO RAN#, RAN#, LOG => -0.1416
0.1717 assume master-cleared machine 2 steps
RAN#, ->H => 0.1717
0.1122 assume master-cleared machine 4 steps
RAN#, SIGMA+, RCL 3, RCL+4 => 0.1122
1.43143 assume nothing else 4 steps
PI, STO RAN#, RAN#, COSH => 1.43143
22.755533 assume nothing else 5 steps
PI, GAMMA, STO RAN#, RAN#, ->DEG => 22.755533
All of them work also on an HP-11C, except the one using RCL
arithmetic that the HP-15C implements but the HP-11C doesn't.
You may also notice that all my solutions make use of the
random number functionality, which is identical for both models except that you can use RCL RAN# in the HP-15C to recall the seed actually stored in the internal RAN# register, which isn't possible in the HP-11C. Anyway, none of my solutions rely on this particular instruction.
Thanks for your interest, sorry for the delay, and
Best regards from V.
