I apologize if my comment came across as disrespectful. It was not meant to be. It was meant to be an affectionate jab at my fellow "Nerds".
I wore a calculator on my belt in the 70's and 80's as well.
We were all taking it in good fun. I know I was!

Re: Leather Case for DM42

I have recently found a very nice leather case for the DM42. A robust & well made leather holder with belt loop. It is an Australian Buckaroo Leatherworks MPPX case. Hey, now I can wear my calculator on my belt again. Just like back in the '70s when I was a nerd! WAS a Nerd?! You say that like it i...

For future books or manuals to be printed on demand, I will certainly try finding another publisher. I recommend other potential authors to do the same.
I can put it on Dropbox for free if you want PDF copies to be available.

Re: 43S News

You might also see it written as: ]-π, π], but I think (-π, π] is the more common style. The round bracket (parenthesis), or reversed square bracket means the value given at that end of the range is excluded from the interval. Whereas a non-reversed square bracket means the value given at that end ...

Re: Benchmark Speed?

A couple of weeks ago, I was reading an old PPC Notes (or something similar), and there was a letter/article about someone doing a large prime number search on their TI-59, and it took about 5 hours. I did the same on my DM42 using a Rabin-Miller prime test wrapped in an outer loop and the whole th...

Re: Benchmark Speed?

Calculators today are a lot faster than 50 years ago! And the DM42 runs somewhat slow in order to conserve the battery. Compare Free42 running on an iPhone, 64-bit code on a fast CPU; the numbers I get for those two benchmarks are 5,593,077 and 481,193. ¡Caramba! Any faster and that machine will gi...

The DM42 definitely IS fast. Depending on the operations you're carrying out, it'll run up to 400x faster than an HP-42S.
Looks like a lot more than 400 times to me!

Benchmark Speed?

Am I crazy or what (my wife votes YES) On https://www.hpmuseum.org/speed.htm there are a couple benchmarks. One for arithmetic and one for trig. I put the following programs into the DM42 and got 21,880 for the Math program and 3,081 for the Trig program! Is the DM42 really that much faster than the...
