Loop of + benchmark now in Articles section Message #1 Posted by gene wright on 2 June 2010, 2:59 p.m. New Benchmark Enjoy! Gene

Re: Loop of + benchmark now in Articles section Message #2 Posted by Glenn Shields on 2 June 2010, 4:01 p.m., in response to message #1 by gene wright It's interesting that the 35s is faster doing register arithmetic (STO + Z) than simply +ing on the stack. Is that because dropping the stack each time uses more steps? regards, Glenn

Re: Loop of + benchmark now in Articles section Message #3 Posted by gene wright on 2 June 2010, 4:25 p.m., in response to message #2 by Glenn Shields Maybe it is due to the different types that might be on the stack. Is it a real? Is it a complex number? Each + might require that to be checked, whereas a STO+ operation might not. Guessing.

The library evaluates functions, sums and numerical integrals from the Equation Writer in double precision for most real functions.

Re: Loop of + benchmark now in Articles section Message #11 Posted by Frido Bohn on 8 June 2010, 5:40 a.m., in response to message #1 by gene wright Hello Gene, congrats, a real great compilation of that simple benchmark across several generations of calculators! However, for the great HP41C/CV/CX one benchmark is missing: MCODE In the book "HP41 MCODE for Beginners" of Ken Emery, published 1985, a 20-step machine code for this 1+ addition algorithm is presented (pages 50-52) which I wont list here. To make things short: Count: ~130 000 This is about 100-fold of FOCAL or Synthetic programs! The 41 was, is and remains amazing
