However not in hardware: this is strange by me: FIX 4 and nothing happens after 27 min, also with SCI 4. Quote:Set FIX 4, and the official HP emulator returns 1,9999 almost immediately.įIX 6 already causes the emulator to run for a while. I thought there was something wrong in Reg but it seems not. Remember, this setting directly influences the accuracy of the result – and thus the execution time. I controlled that all was ok with ON/y^x procedure (all flags and -88.88.88.88.88), I reset also the continuous memory (ON/-) but the same with FIX 4, with FIX 2 I get 1.99 after about 3 mins In hardware HP 15C no result after 27 min now with your program. Without the ENTER I get 1.9999 in iOS in about 2 min (1 min with SCI 4). (11-26-2017 11:01 PM)Dieter Wrote: What are the two ENTERs supposed to do? I would say I am a solid user of the machine. But I hope my input on how I solved the integral on my calculators (and my Dad's) proved useful.
I can't give any advice as I am not a proficient user of the HP- 15C ONLY because I don't own one yet. In a time of 16 minutes and 28 seconds, I stopped the 15C and didn't get an answer as a result. Then I set the 15C to a fix of 4 and attempted to integrate the integral again. In a time of 2 minutes and 42 seconds, I got the answer of 1.99. I set the HP- 15C to a fix of 2 and integrated the integral from 0 to 1. Next I tested your integral on my Dad's (hardware 1987) HP- 15C. I used the integral function that is on the key and I built the equation on the stack with RPN. I did not use the Equation Writer and I was in RPN mode. mode on the HP 50g with a fix of 4, I get 1.9999 in a matter of 3 to 4 minutes. In exact mode, I receive the answer of 2 immediately. I tested your integral on my (hardware) HP 50g.
