HP-41: ELO - Geir Isene - 05-29-2013

Not much, just for the record. Here's a short and sweet program to calculate the gain or loss of your ELO rating.

Just do:


K-value
ENTER
Opponent's ELO rating
ENTER
Your ELO rating
ENTER
Score (1 = you win, 0.5 = draw, 0 = you lose)
XEQ"ELO"

The result is how much you gain or lose in ELO rating.

The program:

001 LBL"ELO"
002 "K^O^Y^W,D,L"
003 RDN
004 -
005 400
006 /
007 10
008 X<>Y
009 Y^X
010 1
011 +
012 1/X
013 CHS
014 RCL Z
015 +
016 *
017 END

Line 002 is included purely as a reminder of how to use the program (the sequence of values entered).

Is there a special reason for using

 10
X<>Y
Y^X
instead of a simple 10x ?

Yes. It is special reason called oversight or stupidity. Pick one :)
