A Very Calculating Treo
I learn new things about my Treo every day and the latest addition to my knowledge follows the discovery that we have nine advanced calculators - including four conversion calculators - built-in as standard.
Simply going to Applications and pressing Calc should bring up what I now learned is just a 'basic' calculator. However, if you press your 5Way Right you'll suddently see this change to an 'advanced' calculator (see below) and subsequent right presses will navigate through all nine advanced options. Pressing your 5Way to the left will take you back to the 'basic' calculator at any time.
Below are screenshots (only top portion as all other buttons remain the same) and definitions of all nine advanced calculators presented in sets of three:
- Math: Advanced mathematical functions such as exponents, roots and logarithms.
- Trig: Trigonometric functions such as sine, cosine, tangent and variants.
- Finance: Financial calculator function such as APR and amortization.
- Logic: Hexadecimal characters in keypad, plus logic functions such as AND, NOT, OR and XOR. In place of Float/Degrees this view includes options for class (bin, oct, SDec, UDec, hex) and bits (8, 16, 32).
- Statistics: Statistical functions such as Sum, Factorial and Random Number generator.
- Weight/Temp: the first of four conversion calculators this one provides weight and temperature conversions for English and metric values.
Using the conversion calculators:
For example, to perform a conversion from 32 degrees centigrade to Farenheit simply type the number 3 and 2 in the calculator pad, then press degreeC then degreeF and up pops the answer. The same process applies for all other conversions.
- Length: Length conversion for metric and English values.
- Area: Area conversions for metric, traditional and English values.
- Volume: Volume conversion for metric and English values.
I know of more than one occasion where these could have come in handy had I known about them before... That will teach me to read manuals...

I put in the info in the palm finance caculator and then I put the same info in excel and get a different answer. What gives???
Thank you, thank you! I have been struggling with trying to use the Treo 700 and not being able to figure it out. I didn't know all of the other calculators were on there. More info in the user guide would be very helpful! I'll have to see if I can figure this out now. Mary
OK, so the bottom line is that there is no way to solve TVM problems using only the "calculator" user interface. Sooner or later you must click on the "Edit" icon and use the "form" to clear the unknown value and tap the Solve button. And there is no way to "Recall" any of the values you have entered using the calculator keys; again, you must use the Edit icon to see the previously entered values. So, I conclude that this is another example of lost functionality when moving from a Graffiti device to a Treo device. Nevertheless, once you break the code, and stop tearing your hair out and feeling like you must be mentally defective, it's a really sweet little calculator.
Merwyn:
Tap on the "Edit" icon and enter these values.
Assuming interest is calculated monthly:
P/Yr: 12
PV: [blank]
FV: 25000
Pmt: 0
APR: 5
N: 240
Tap on Solve (for PV).
A: $9,216.11
Like I said, a sweet calculator.
Kevin,
I tried what you did and got the same answers. See Post #29 for the Treo answer. Then try this in Excel:
=PV(5%/12,240,0,25000)
You should get the same answer: $9,216.11.
I am sorry, I don't follow this for a Treo 700p. Not sure what you mean by 'hit solve" or "edit key".
