[wp-34s] h.mmss number entry
I'm having difficulties entering numbers in the hh mm ss format.

The decimal to hhmm works fine with the H.MS function (e.g. 1.5 H.MS -> 1 30' 00"
However how do I enter 1 hr 30min?
The H .dd does give me nothing useful. Assuming a format of hhhhmmss.dd would mean entering 13000.00 H .d -> shows 13000
Entering 1.30 gives me 1.3

I just want a simple way to add time sheet data in the form of 1hr 15min + 3 hrs 35min + 2 hr 58min. Having the result back in hr and minutes.

Thanks for your help

Try the H.MS+ function.

Thanks for the quick reply.
I have tried that one and it does work as expected but it's pretty awkward to get to.
I suppose I could write a little macro/program to make it a bit more user friendly.

"ahagele" is right. There seems to be no conversion function from times entered on
the keyboard in hours, minutes, and seconds to hours and fractional hours format.

For instance on an HP-15C if you enter 1.3 and press >Hours it gives you 1.5 converting the 30 minutes into half an hour. I don't think there is a similar conversion function on the WP-34S is there?

Try [->] f H.d.

We couldn't support key assignments

That does not work in the expected way. 1.3 [H .d] -> 1.3

Don't forget to press the [->] conversion key before [H.d].
The key sequence should be: 1.3 [->] [f] [H.d]

This is just a display function for your convenience. It does not change the number in X at all. This is not a conversion function!

1.5 [f] [H.MS] => 1°30' 0,00"

Press [←] to clear the display and you'll see the original 1.5 again. Nothing has changed.

If you want to convert 1.5 hours to 1 h 30 minutes you have to use the conversion functions. These start with a [→], see below.

Like on all calculators I know of, the format is hh.mmss. So you enter 1.30 or 1.3000.

Sure. Again: the format is not hhhhmmss.dd but hh.mmssdd – same as the good old 67 or 15C. The 34s has the conversion functions between h.ms and decimal hours directly on the keyboard. But you have to know how to handle them, so please read the manual. Here you use the "convert" key, the big right arrow [→] beside the [D] key. It works like this:

1.30 [→] [f] H.MS returns 1.5 hours
1.50 [→] [f] H.d   returns 1.30 (i.e. 1 h 30 minutes)

You can even briefly see the →H.MS and →HR function names appear in the display. They are the same as the ones on the keyboards of classic HPs.

Here you can use the dedicated H.MS+ and H.MS– commands. They are buried in the X.FCN menu. So once again: please read the manual. The 34s is an extremely capable and powerful device, but you have to know how to handle it.

Here is your example:

1.15 [ENTER] 3.35
[h] [X.FCN] ...scroll down to H.MS+ by pressing the letter H and [↓] [↓] [ENTER]

=> 4.5000

Add 2 h 58 min to this:
2.58 [h] [X.FCN] ...H.MS+ now shows up directly [ENTER]

=> 7.4800

Of course there is. But you have to know how to use it. There is no key labelled →H or →H.MS.
On the 34s there are many conversion functions avaiable through the [→] (convert) key right beside the [D].

Press 1.3 [→] [f] [H.d] and the display shows →HR while you hold down the last key. ;-) The opposite direction is available with [→] H.MS which calls the →HMS function.

And there is more:
[→] [g] [RAD] converts from the current angle unit to radians (→RAD function).
[→] [g] [DEG] converts from the current angle unit to degrees (→DEG function).
[→] [g] [GRAD] converts from the current angle unit to grads (→GRAD function).

In these cases the [g] can even be omitted, so [→] [RAD] is fine as well.

Suppose you are in radians mode and the result of a calculation is an angle of 0,6 rad. What's this in degrees, minutes and seconds?

[→] [g] [DEG] => 34,3775°
[→] [f] [H.MS] => 34°22'39"

So the functions are there, and there are even some nice shortcuts for using them. But you have to know them, they are not intuitive.
That's why for everyday work I prefer my 35s. Or the 31s. The latter has the same conversion key [→] but H.MS+ and H.MS– are directly on the keyboard.

RE: [wp-34s] h.mmss number entry
Ahh Yes!! Now I remember. I went through this a few years ago when I first started using the WP-34S. I had forgotten about the "Convert" -> (Arrow) key prefix before pressing f H.d

Thanks for reminding me about the Convert key. I knew that the WP-34S had every function imaginable included. I just forgot the subtleties on how to get to a few of them.

Thanks Again, Barry

Now that's a trick for young players. The 'conversion key' was the magic ingredient. I misread the '->' as in going to / doing, not an actual key to press.

Thanks for that.
