IMPORTANT NOTICE:
-----------------
To preserve conversion rates database you already have, before installation
of the version 3.0 or later, you must:
1. Do a Hotsync
2. There will be a file "CurrC_DB.PDB" in the "\pilot\your_pilot_user_name\backup"
   directory. Copy it to a safe location for later use.
3. Install new CurrCalc
4. Install "CurrC_DB.PDB" from where you saved it.

1. Overview
-----------
Currency Calculator is a combination of unit converter and standard
calculator with 12 digits precision, very easy to use. Up to 15
conversion categories can be defined with 200 items in each. Any
category can also serve as a group of constants.

Conversion functions:
---------------------
- 15 user definable unit (and/or constant) categories)
- Units can be edited by just one tap on the little square next to
  the unit's name
- All units of the same category can be recalculated at the same time
- All kind of temperature conversions between F (Fahrenheit),
  C (Celsius) and K (Kelvin) degrees
- Angle formats conversion from HMS (hours, minutes, and seconds) to decimal
- Julian day to Gregorian calendar date conversion
- Time->seconds and Seconds->time conversion
- compatibility with the EURO - please read the "Euro.txt" file

Mathematical functions:
-----------------------
- Standard: +, -, x, /
- Trigonometry: sin, cos, tan, asin, acos, atan
- Exponential/Logarithmic: x^2, y^x, 10^x, e^x, log, ln, 1/x, 1/x^2, x!
- Date: Date +/- number of days, number of days between two dates
- Other functions: percentage calculation, area and circumference of
  a circle, constants Pi and Pi/2

Other features:
---------------
- 12 digits math. precision.
- Number of decimal places can be defined in the range from 0 to 11 and there
  is also "Float" (F) option for displaying all possible decimal digits
  (without ending zeros).
- 10 user memories. You can perform arithmetic operations (+, -, x, /)
  with each memory
- Numbers are displayed with thousand separators. Comma (","), dot ("."),
  space (" ") or apostrophe ("'") can be set as thousands separator with
  "Prefs" application ("Formats" panel)
- Dates should be entered according to the settings in the "Formats" panel
  of PalmPilot's "Prefs" application, but without delimiting characters
  between month, date and year
- Copy/paste between display and clipboard
- Each category names and values can be exported/imported to/from Memo
  Pad memo. Fields are delimited with TAB character. That way, you can
  export (for example - currencies) to Memopad memo, edit them on your
  desktop computer, and after hotsync import them to CurrCalc.
- Date and time calculations
- Multiple multiplication and division with the same number
- "Constants" mode - current category serves as a group of constants. If you
  append "_C" to the category name, than CurrCalc will automatically enter
  constants mode each time you choose that category.
- Reversed unit conversions - for many users outside the United States
  conversion algorithm implemented in CurrCalc is not adequate. Those
  users can enable reversed conversions using "Preferences" menu option.
- "Help" mode - when you put CurrCalc in "Help" mode (with menu option
  "Help"/"Help mode ON/OFF", or with menu shortcut "/h"), tap on any
  button on the main screen invokes help for that button. To turn off
  "Help" mode, choose again "Help"/"Help mode ON/OFF" menu option.
- Binary calculator (hexadecimal, decimal, octal and binary input modes)
- Daily repeating alarms
- If CCTime is installed, then dual time display can be viewed

2. Installation
---------------
Distribution includes the following files:

CurrCalc.prc  -	Main application
CCHelp.prc    -	"Help mode" plug-in
CCBinCalc.prc -	"Binary Calculator" plug-in
CCAlarm.prc   -	"Alarms" plug-in
CCTime.prc    - World time database editor/viewer
CCTimeDB.PDB  - Database for CCTime with more than 190 cities
currc_db.pdb  -	Database with predefined units. Please notice that
		"Currencies" category is empty
CurrCR_DB.PDB - Database prepared for use with "Reversed unit conversion"
		preferences option.
Readme.txt    -	This file
Euro.txt      - How to use instructions with Euro currency. PLEASE READ IT!

The only file you must install is CurrCalc.prc, but for first time users,
it is good to install CCHelp.prc also. After learning how to use CurrCalc,
CCHelp.prc can be deleted.

Required files can be installed with INSTAPP.EXE installation tool.

3. Instructions
---------------

IMPORTANT: The easiest way to learn how to use CurrCalc is to turn
"Help" mode on and tap ALL OVER THE SCREEN!!! There are some screen
areas that doesn't look like buttons, but act like buttons!

Main form menu options
----------------------
"Conversion Rates" - displays form for entering current category unit
names and rates

"Preferences" - displays form for enabling reversed unit conversions

"Registration" - form for entering registration information which will be
supplied to you upon registration

"About CurrCalc" - displays information about author and user
(if it is registered)

"Help mode ON/OFF" - turns help mode on and, if help mode is active, turns
it off


"Conversion Rates" form menu options
------------------------------------
"Export to Memo Pad" - exports units in current category to Memo Pad memo in
TSV (tab delimited) format. CurrCalc will append category name and current
date to first line of exported memo.

"Import from Memo Pad" - imports names and values from Memo Pad memo.
Fields can be delimited with any number of tabs. TAB delimited comment
may be added to each line of text to be imported. CurrCalc has a limit
to display only first 100 memos in chosen category.

"Sort Records" - alphabetically sorts units. You can also sort records
manually - just drag the unit to the desired position.

Entering values - standard unit conversion
------------------------------------------
Please read the "Euro.txt" file for instructions of how to use CurrCalc
with Euro.

If:
100 USD  = 185.55 DEM = 662.00 Kn (Kn - Croatian currency)

then you must enter:
USD = 100.00
Kn  = 662.00
DEM = 185.55

Another example:
----------------
If:
1 foot = 12 inch = 304.8 mm

then you must enter:
inch =  12.0
foot =   1.0
mm   = 304.8


Entering values - reversed unit conversion
------------------------------------------
If:
100 USD = 640.00 Kn and
100 DEM = 353.00 Kn and
100 ATS =  50.00 Kn

then you must enter:
Kn  = 100.00
USD = 640.00
DEM = 353.00
ATS =  50.00

------------------
You can use CurrCalc as a standard calculator.  When the '=' button
changes to 'Convert', you can either do a currency calculation by tapping on
'Calc', or another standard operation by tapping on the operators (+ - x
or /) or by entering a new number.

Percentage calculations can be done as follows:

If you want to calculate percentage P of a number N, your keystrokes will be:

N x P %

If you tap on "+" (or "-") button after the "%" button, calculated percentage
will be added (or substracted) from the given number N.

You can get 100% of a given value with:

N / P %


Constant multiplication and division
------------------------------------
You can do a multiple multiplication or division with the same number.
1. Enter a number
2. Tap twice on the "x" (or "/") button
3. Enter the second number
4. Tap on the "=" button

Repeat steps 3. and 4. as long as you wish.

Example:

5 x x 6 = (the result is 30)
2 = (the result is 10)
15 = (the result is 75)

Another example:

200 / / 2 = (the result is 100)
5 = (the result is 40)
40 = (the result is 5)

-------------------
Tapping on the arrow between unit names will reverse direction of
conversion. When you do this, the arrow '-->' changes to '<--'.

You can edit previously defined unit without using the "Conversion Rates"
menu option. Tap on the little black square left (for left unit) or right
(for right unit) of the unit name.

After tapping on "All" button, unit conversions are run on all
defined units and results are displayed in a separate window.

Tapping on the "+/-" button changes sign of displayed number.

To start exponent entering mode, tap on the "Exp" button. Sign of the
exponent can be changed with "+/-" button.


---------
You can convert angles from the HMS to H(decimal) form and vice versa.

Example:

Your input: 25.3052 (25 degrees, 30 minutes, 52 seconds)
Tap on "Trig" button and then "HMS->" button
Result is: 25.514444 (25.514444 degrees)

Another example:

Your input: 38.26 (38.26 degrees)
Tap on "Trig" button and then "->HMS" button
Result is: 38.1536 (38 degrees, 15 minutes, 36 seconds)
