About
To install this utilities you should synchronize
the "MEGACALC_XXX.prc" application to your
device. Files can be installed by using the
Desktop S/W or just any other application.
Note! If you have previous version of
MegaCalc installed on your device you should delete it
before installation. You should install only one
.prc file depend on your device type.
- For color devices: Tungsten T/T2/C/E, Zire 71,
Sony Clie' UX40/50 and Acer s50/s60 (Palm OS 5.0 or
greater) – MEGACALC_HR_COLOR_65K.prc
- For color devices: Sony NX60/70V, Palm Tungsten T3
(Palm OS 5.0 or greater) –
MEGACALC_HR_PLUS_COLOR_65K.prc
Note! Please pay your attention to the fact that "MEGACALC_HR_PLUS_COLOR_65K.prc" file may not operate on some Palm Tungsten T3 devices.
This is due to some technical aspects for the earlier versions of this device.
We recommend you to install temporary "MEGACALC_HR_COLOR_65K.prc" file onto such devices.
As soon as this problem is determined and the official patch from the device producing company comes out, we will let you know at once and you will be able to use the full version of this program.
In any case thank you for your being patient.
- For color devices: Sony NR60/70V –
MEGACALC_HR_PLUS_NR70.prc
- For color devices: Treo 600, ... (Palm OS 3.5 or
greater, 160x160 devices) –
MEGACALC_LR_COLOR_256.prc
- For gray devices: Palm Zire 21, ... (Palm OS 3.5
or greater, 160x160 devices) –
MEGACALC_LR_GRAY_16.prc
Note: To run this application MathLib is
required. If you don't have MathLib on your device you
should install the MathLib.prc from the MegaCalc.zip
file. MathLib should be only on device memory itself.
Do not install it on any extension cards.
Note! If your device is not listed among
those that are supported by MegaCalc v.2.3.3, use
2.3.2 version that is available here.
The MegaCalc application is a multifunctional
calculator designed to implement the same operations
as an ordinary calculator does. It fulfils basic
arithmetic operations, such as addition and
subtraction and also the functions of engineering
calculator, for example determination of logarithms
and factorials. Now you don't have to carry some extra
calculator with you.

This mode allows you to
convert all possible values without any
difficulties. |

|
Sample operation:
- Select the
desired value, for example "Lenght" - Select
the desired parameter (From), which is needed to
be converted - Enter the sum of the parameter
being converted in the field "Value" -
Select the (To), to which you want to
convert.
"Swap" - This is change
current "From" and "To" units. "Clear" -
This is set value to
0.
|
|
"Currency"
mode enables the user to convert all the main
types of currencies and also those currencies that
were entered by the user. |

|
Sample operation:
- Select the desired
currency (From), which is needed to be
converted - Enter the sum of the currency being
converted in the field "Value" - Select
the currency (To), to which you want to
convert - Enter the exchange rate in the field
"Rate" - Set the necessary bank interest
for this operation (Comm). This particular value
depends fully on the bank. If this value is not
available in the bank, set it to 0%.
"Edit cur..." - The description of this button
is given bolow "Swap" - When this button is
pressed, "From" and "To" switch places.
|
 |
"Edit
cur..." This window allows to add new
currency (monetary unit) or to delete/rename
the currencies available in this
list.

This mode will be very helpful when you visit
cafes, restaurants and travel by taxi,
etc. Here is an example: you’ve got $80 bill in
the restaurant. You need to calculate the sum of
money you should leave as a tip. So, in the “Bill”
field enter 80, then choose the percentage of the
tip in the drop-down list “Tip:” (in our case let
it be 15%), then in the "#Prs:" drop-down list
enter the total number of people who are
accompanying you if you intend to share the bill
with the others, however in our particular case
we’ve got only one person – You. Thus you
are to pay the waiter
$92.

This is
simple mortgage calculator. |

|
Loan amount - The total amount of the
money that you have borrowed. Loan term
- The number of years or months you have to pay
the loan. Interest rate - The exact
interest rate on your mortgage. Annual
tax - Property tax is also called real estate
tax. This tax is paid to the local taxing
authority or municipality. Annual
insurance - Also called property insurance,
homeowner's insurance protects the homeowner from
weather-related damage, as well as potential
liability from events that occur on the property.

decimal mark character as defined in your
PalmPilot's Preferences number format
setting. Float mode - In this mode
the number in the range of (1е-15, 1е15) is
displayed “as it is” up to 15 signs. The number
that exceeds the pointed limits is displayed in
the Scientific exponential mode. Scientific
exp.mode - In this mode the number is
displayed in the exponential form, mantissa to be
constantly < 10 Engineering exp. mode
- In this mode the number is displayed

Description:
In this window you can look through all 4 stack
registers (X, Y, Z, T), and also perform simple
operations. |

|
- Upward cyclic shift of the stack. The
number transfers from X register to Y register,
from Y to Z, from Z to T, from T to X.
- Downward cyclic shift of the
stack. The number from register T transfers to Z
register, from Z to Y, from Y to X, from X to T.
- Drop stack operation.
The number in T register remains constant, the
number from T register transfers to Z register,
from Z to Y, from Y to X. The number that was in X
register is lost.
- Swap
the values of registers X and
Y

Basic
adjustments of the MegaCalc
application |

|
Use Calculator icon for launch - In this
mode, when the button "Calculator icon" is pressed
MegaCalc launches instead of the standard
calculator
PalmOS. Default
display mode - determines number
representation mode, which will be set after the
MegaCalc (Floating, Scientific exponential,
Engineering exponential, Fixed) application is
launched. When "Last" mode is selected, the
program will set the mode which was previously set
before the exit. Default calculator
mode - determines MegaCalc launching mode
(Simple, Engineering, Convert). When "Last" is
selected, MegaCalc will be launched in the mode
which was previously set before the
exit. Accuracy in fixed mode - specifies
the number of decimal digits in the mantissa of
the decimal calculation
results. Entry--system logic -
sets the data input order and calculation
sequence. It can be: 1) Simple. In this mode
the data and the operators are entered in the
consequence in which they are written, the
calculations are performed without the priority of
the operations, that is the expression 1 + 2 * 3
is entered as [1][+][2][*][3][=] and will give 9
in the result. So, addition is performed first,
and then comes the operation of multiplying. To
perform the operation of multiplying first place
you need to enter the expression as
[2][*][3][+][1][=], or as
[1][+][(][2][*][3][)][=]. In both cases we will
get 7 as a result. 2) Algebraic. In this mode
the data and the operators are entered in the
consequence they are written, however the
calculations are performed regarding the
operations priority. That is the expression 1 + 2
* 3 is entered as [1][+][2][*][3][=] and will give
7 as a result. Thus, multiplying is proceeded
first (with the higher priority), and then the
operation of addition (with the lower
priority). 3)RPN (Reverse Polish Notation
). This mode is a postfix mode (the operators are
entered after the data). It enables to do without
the parentheses during the calculations. The
expression 1 + 2 * 3 is entered as
[1][ENT][2][ENT][3][*][+] and will give 7 in the
result, or as [1][ENT][2][+][ENT][3][*] and will
give 9 in the result.
|
|
 |
When selected, this window allows scanning the
entire list of the performed operations.
This mode stands for the specific log-file to
analyze and check the accuracy of your
calculatons.
