San Valentin

Good news, everyone !

Today is my name day so here's my Valentine for all of you:
(Caveat emptor: video with sound, check volume or use headphones if at work but do not mute for maximum laughs)

I Will Always Love You

Incidentally and to stay on calcs/math topic, you may want to check with your favourite HP calculator which can do multiprecision floating point that this very date in yyyymmdd format, namely 20180214, does quickly appear in an irrational (presumably normal) number:

Sqrt(184395) = 429.412389201802141017496...

Have a happy St. Valentine's day and best regards.
V.

Hi there !

Thank you very much, Ángel, Eddie, Luigi and Joe, for your kind wishes, much appreciated !

After 2^5 years married I'm still quite the romantic soul, which is good. I'll try my best to contribute more frequently to the forum though I've still not solved to my satisfaction the essential issue of how to make my Hp-related materials available online.

By the way, Joe, very nice your expression including the 2018/02/14 date. As it uses two operations (^ and /) and eight digits (3,3,1,5,2,5,8,7) to render an 8-digit sequence (20180214) it has a "Simple Merit Value" of -(2+8-8) -2. Mine has a SMV of -(1+6-8) = +1., which is better ... 8D

Here's another one:

Sqrt(22008840) = 4691.3580123456789961013...

which again has SMV = -(1+8-10) = +1.

Actually the Full (not Simple) Merit Value also takes into account the number of digits before the sequence begins, else you'll find any sequence in, say, Sqrt(2) by simply computing enough digits and so the SMV could be arbitrarily large, assuming Sqrt(2) is a normal number in base 10 but I digress..)

Thanks again and best regards.
V.

sqrt(1088270) = 1043.201802145682645...

This has a high Full Merit Value, yes?

Amazing, thanks Valentin and Joe !
Can you please just give us simple mortals some little indications on how you find these amazing expressions?

Thanks Valentin, awesome !

Please think of me when you have a minute, regarding your wonderful EQUEEN 42s program

By the way, you once showed me how to open mind mind to other paradigms, with Sharp Basic computers. I would be grateful if you could share with us your opinion on the HP Prime. I was quite reluctant initially, it took me 4 years to buy one... But now that I got used to it, I think HP is really back with this one, great hardware and software quality. Its Pascal-like HHPL language is similar to Basic, well integrated with math objects, and flexible. I think it is the dignified successor to the HP-41 and the HP-71B. What do you think ?

Cheers

... not to mention the DM42! That new model is waiting for Valentín, as one of the green berets of the ol'reliable HP42s :0)

Yes it does, though it still doesn't reach a 5 in a 0-10 scale (mine doesn't either).

Now consider this:

Sqrt(1997443) =

1413.30923721597461297613912310041985464922196007087271143172518818493

12429086750031769658291833377472798278417039...

¿ Any comments on the underlined 10-digit sequence ? (;-D) ...

Best regards.
