HP 15 Savage Benchmark
I simply entered the code, now I am running it. For the HP-15C it is around 97 minutes, I am curious of my (t)rusty old '11.

I was curious too so I ran this today. The code I used was:

Code:


001 LBL B
002 STO I
003 RAD
004 FIX 9
005 0
006 LBL 0
007 1
008 +
009 SQRT
010 X^2
011 LN
012 e^X
013 ARCTAN
014 TAN
015 DSE
016 GTO 0
017 DEG
018 RTN

The only difference to the HP-15C code is storing the decrement counter in the index register instead of register 0. The result was 2,499.969898 in approximately 5,235 seconds, quite a bit quicker than the previously posted value for the -15C.

Interesting... I would say the same - faster, but not 2.6 times faster. How long does a value display on PSE?
