5 RADIANS
10 A=1
20 FOR I=1 TO 2499
30 A=TAN(ATN(EXP(LOG(SQR(A*A)))))+1
40 NEXT I
50 PRINT A
New Bench ? :-)

Hi gileno, have you missed this question ? ;-) A good idea. After having a benchmark for a non numerical problem, I also thought about a simple but convincing numerical benchmark. I think the basic problem is to find an usable program for testing. Probably a mix of simple float calculations and some mathematical functions are not bad. An example for a simple float test:
0->A

This is a well-known benchmark usually known as the "Savage" benchmark. I have run it on several HP models in the past, and I will post results if I can find them in my old (deeply buried!) papers. I would definitely enjoy seeing results from other machines and look forward to many submissions!
Thanks, ▼

Yes, this has been discussed here already:
The original benchmark program can be found here (Page 12, Column 1): http://www.amigau.com/68K/dg/dg25.htm Regards, Gerson.

Well, 50G w/HPGCC @12MHz takes .52s and returns 2500 Not sure exactly how many digits are being used internally. Anyone know? TW ▼

With the SDK compiler, the FX-9860GSD takes 0.42 seconds. Why 12 MHz on the HP-50G? Is there another reason except for less power consumption? ▼

Its just the default speed when compiling. You have to add in a sys_slowOff(); at the beginning, or modify a loader file to not mess with system speed. Keep in mind that there is always a .05-.06s penalty to START the program in saturn land. That is how long an empty program takes to run. TW

A couple of timings: HP-71B: 344.82s HP-49g+: 63.48s (using BINTs for loop variables) Both return 2499.99948647 like all Saturn-based HP's.
