Which programs do you actually use in your calculator?

[brickviking]

On my calculator? Depends on which calculator. The upgraded fx9750gII has the grocery program I've referred to before in these forums, and also has a PCH (percentage change) program I wrote. i.e. feed it two figures, it'll tell you the percentage change (both up and down) between the two figures.

The grocery program has a rather crude sales tax calculator embedded as part of the source, formula looks a bit like this (with apologies for the BASIC):

Code:


BEGIN
'Initial tax rate percentage, adjustable
15 \-> N
(1-(100/(100+N))) \-> O
"Total"?\->G
Print "Tax: ",G*O
END

I don't actually know a better way to calculate that rate, though I'm pleased I worked this out for myself <grin>.

For apps on the 9750, I've also installed:

• an editor
• INSIGHT (a memory viewer)
• FTune (for when I just have to speed things up)
• Help applet found on the Slim, thankfully it works on my non-Slim calculator.
• Physium (from Casio)
• Geometry (also from Casio)
• a Clock. Weird, as it never gets much use, but the Casio actually has an inbuilt timer.
  

The HP50G has another couple of programs supplied to me from a member on these forums (thanks) and somewhat fitted to purpose, related to summing grocery totals for a month (TMonth) and year (TYear). I think I sort of understand how they work now, but at least initially, it was like trying to read guacamole with a laser. And I'm still trying to debug what's wrong with an addition I made. Never mind, that's part of the fun of RPL.

• Programs from Mervin E. Newton's tutorial, a good resource for people starting out.
• A recent PI1K program (pi with a certain formula).
• BTMON (which reminds me, batteries never last as long as I want, I have to change these)
• PI50G
• HPAUR programs
• HLP49 - so useful I've finally ASN'ed it to a USER key, my one and only user key so far.
• Others I can't remember.
  

And whats an alot anyhow?
