Epoch time conversion

hi, I've modified a program of Bill Duncan intended for HP 41CX to get Epoch Time from a date and convert Date/Time into Epoch Time. In this post on MoHPC you can read the thread. If you are interested, the version for HP Prime is in the Program Library MoHPC . I've modified the program for DM42 and...

I am surprised something as superficial as the off image as induced so much excitement
the reason is that some of us (me) are like a kids (a 54's kid here) and we amuse with those aesthetic features :)

After ARCL, press the period key then IND and then ALPHA and choose your letter.
ok!
ok with period, and ST X beside IND.

I should read again the HP-42s manual!
:-)

Now the program works as expected. I saved it in the program folder...

Thanks a lot!

Re: ON and off (images)

In fact, I was considering posting a request to enable quick viewing of and cycling through the Off images. Something like add a fifth option to the “File” menu: 5.

Re: Show all digits in binary number

There's no built-in way to do that, but you could use a program that does something like this: LBL "BVIEW" CLA BINM ARCL ST X DECM PROMPT END ok, Thomas. I'm trying it. I don't remember how to input ARCL ST X If I put ARCL from "CATALOG -> FCN" then choose X from soft menu I get ARCL "X" but so the...

Show all digits in binary number

hi, let's put a binary form of i.e. -15180, we have 14 "1" and then only 12 significant digits to the right, ok. We have X: 11111111111111... We can see it with Shift-Show but for a while (...00010010110100). I would like to see the whole number without keeping pressed Show. I don't remember how to ...

I confess: I'm doing ON/OFF sequence more times to see drawn OFF Images to appear: too nice! :-)

I have too much free time now. I made a PDF of the DM42 QRG with bookmarks, just for the fun of it. If there's a better one out there, let me know!

It's too big to attach here (527 Kb), so if you're interested, I'll email you a copy.
please, Tom, email me.

Re: Sun program help

The SUN program on my web site calculates the height of the sun above the horizon, given the axial tilt of the planet, the observer's latitude, the season (expressed as an angle, where 0° is the winter solstice), and solar time of day. It is based on a very simplistic formula, which assumes the Ear...
