General
theCalc consists of five Modes:
 It contains a sophisticated Scientific
Calculator using RPN (Reversed Polish Notation after
Polish mathematician Jan Lukasiewicz in the 1920's)
 It contains a Unit Conversion
tool to convert between lots of units and currencies.
 It contains a Base Conversion utility
(e.g.. Hex to Bin).
 It contains two IP Calculators: a Network
Calculator and a Subnet Calculator.
 It contains a Finance Calculator
 for Loan and Savings calculations.
 It contains a locationbased Tip Calculator
to quickly calculate the tip based on country and satisfaction,
and easily split the bill.
 In addition, theCalc contains a Mini
Calculator, floating on top of the other modes and other
applications  designed to be small, helpful and easy to
use for fast calculations.
Using theCalc
 The current mode is always visible on top of the displayed
page.
 To switch between the different modes of theCalc, simply
navigate between the modes using the
buttons, or use the "Mode" menu at the bottom
of the application.
 You can copy and paste results between the edit fields
of the various modes. To bring up the Edit popup menu, select
the text you want to copy and the press the stylus down
on the selection for a few moments.
 The Mini Calculator can be opened
via the "Tools" menu.
 The Options dialog can be opened via the "Tools"
menu. It allows you to set a custom currency for the Unit
Conversion, and you can select whether theCalc should
appear in the Start Menu.
 To get help about theCalc's functionality, select "Help  Index".

Scientific Calculator
Allows you to perform complex calculations using Reverse Polish
Notation (like scientific HP calculators).
 Example 1: 34+22
34 [<']
22 [<']
+
=> Result: you have 56 on the strip
 Example 2: 2*(3+4)
3 [<']
4 [<']
+
2 [<']
*
=> Result: you have 14 on the strip
 Each time you enter a number, press
to store it on the strip.
 When you have the result on the strip (e.g. 56 for Example 1),
you can use this number to continue calculating or you can
just leave it on the strip for later calculations.
 There are some special buttons helping you to use the
strip:
... deletes the lowest entry on the strip.
... duplicates the lowest two entries on the strip  handy
if you want to make different calculations with the same
numbers.
... clears all entries on the strip.
... corresponds to the "Enter" key  puts the
entered number on the strip; if the input field is empty,
the lowest entry is duplicated.
 DoubleClicking on an entry in the strip puts that number
into the edit field.
 To convert an angle between Rad, Deg and Grad,
simply enter the value in the edit field and then select
the desired angle measure from the radiobuttons above.
Note: The conversion is only applied to the value
in the edit field, but not to the values on the strip.
 Example 3: If the current
angle is set to 'Deg', enter 90 and then select 'Rad'
=> you get 1.57079... in the edit field, which is
equivalent to pi/2.
 On the left side of the strip is a TreeView with sorted
Operations you can perform:
 Operator: common functions
x!, 1/x, sqrt, x^2, x^y, e^x, 10^x, ln, log
 Trig: trigonometric functions
sin, cos, tan, asin, acos, atan, sinh, cosh,
tanh
 Logic: Boolean functions
not, and, or, xor, xnor
 Misc: miscellaneous functionality
rand
 Const: constants
e, pi
To apply a function to a value, either press the
button or doubleclick on the operator.
If the edit field contains a value, the operator is applied
to that value; otherwise it is applied to the lowest entry
on the strip.

Mini Calculator

A small floating calculator allowing you to do fast calculations.
 The MiniCalculator uses the conventional notation (as
opposed to RPN used for the Calculator).
 The MiniCalculator comes especially handy if you need
to do some small and quick calculations for the various
modes of theCalc, since it floats on top of the application.
 The MiniCalculator can also float on top of any other
application, thus allowing you to do calculations on the
fly and paste the result anywhere easily.
 You can use Copy & Paste to transfer values from input
areas (e.g. edit fields) to the MiniCalculator's input area
and vice versa.
 When performing a calculation, look at the title bar:
there you can see the calculation you have entered till
now. Press
to calculate the result.
 The
button contains a menu holding special Operators like sin,
COs, rand, etc. (like the Operator tree of the Scientific
Calculator). It also contains an option to Hide/Show the
main application, so you can use the MiniCalc by itself.
 Since you can copy and paste result from and to the MiniCalc,
it comes extremely handy with the various modes of theCalc
as well as with external applications like MS Word or Excel.

Unit Conversion
This tool allows you to convert between different units and
European currencies.
 Use the 'Category' list to select the type of unit you
want to convert.
 Enter the number in the edit field below, and select the
base unit.
 The value is then converted to the other units of the
same category, each displayed below.
Example: Select Length as Category,
enter 10, select 'meter (m)' as base unit > the area below
displays various length units which correspond to 10 meters.
 Since the "Currency" category contains only
Euro currency countries, you have the possibility to add
an additional currency (and its rate) via the "Tools
 Options" menu.
 For each entry in the results list, you can open a popup
menu which allows you to copy either the unit name, unit
value or both.
To top

Base Conversion
Allows conversions between different numerical bases  decimal,
hexadecimal, octal and binary.
 Just enter a number in any base format and it will instantly
be converted to all other bases.
 Example: Enter 34 in
the 'Decimal' field =>
Hex: 0x22
Bin: 100010
Oct: 42
 You're not limited to the four builtin bases, but can
also enter any custom base (between 1 and 62) you need for
conversion.
 If you enter letters or digits that are not contained
in the respective base format, an "Error" text is displayed
instead of the converted numbers.
Valid ranges for the different bases:
Decimal: 0..9
Hexadecimal: 0..9, a..f
Binary: 0,1
Octal: 0..7
 The following letters are used for custom base: 0..9 A..Z
a..z, hence custom base can range from 1 to 62.

IP Calculator
The IP Calculator actually consists of a Subnet
and a NetworkCalculator:
Subnet Calculator
 Calculates the number of Hosts, Subnets and the Subnet
Mask for your network, based on the following entries:
 IP Address
 Network Class
 desired number of Subnets or Hosts
 After filling in the IP address, network class and the
number of subnets (or the number of hosts), press the
button to compute the results.
 The resulting Subnet Mask is displayed in both the dotted
decimal notation (e.g. 255.255.0.0) and as the number of
bits in the Subnet mask (e.g. /16).
 Explanation of terms:
Hosts:

the number of nodes per Subnet 
Subnets:

the number of subnetworks 
IP Address:

the TCP/IP network address 
Network Class:

Class A  max. 16777214 hosts
Class B  max. 65534 hosts
Class C  max. 254 hosts 
to top
Network Calculator
 Calculates the Network Address, the Broadcast Address
and number of bits in the Subnet Mask based on the following
entries:
 IP Address
 Subnet Mask
 The parameters used for the Subnet mode are automatically
used for this mode, but of course you can modify them any
time. After filling in the IP address and the Subnet mask,
press the
button to compute the results.

Finance Calculator
The Finance Calculator can be used for two purposes: as a
Loan Calculator (main purpose), or as
a Savings Calculator.
Loan Calculator
Calculates the total amount you have to repay, and how much
interests you pay for the loan.
 To calculate monthly payments, enter your loan amount,
the current interest rate and the number of years you plan
for repaying the loan.
 To calculate the loan amount, enter your desired monthly
payment, the current interest rate and the number of years
you plan for repaying the loan.
 Press the
button to see the results.
 The top of the results sum up your parameters: the loan
you took, the period of time to repay, the interest rate
and the monthly payment.
Below, you see the annualization table  a detailed list
of how much you have to pay each year, and how high the
interests are for that period. The bottom of that table
sums up how much you effectively paid and how much of that
sum were interests.
 In addition, you can also enter a monthly or yearly "Optional
Prepay", representing a sum you want to spend in addition
to the monthly payments, to amortize your debt more quickly.
 If you have entered an optional prepay, the time you effectively
saved is displayed at the bottom of the results.
Example
1: If your loan amounts to a total of 10000,
and you want to repay in 5 years, having an interest
rate of 5% means that you'll have a monthly payment
of 188.71. After these 5 years, you will have paid
a total sum of 11322.74, of which 1332.74 were used
just to cover the interests. 

Example
2: If you want to repay 100 monthly over 5
years, having an interest rate of 5% means that you
can take a loan of 5299.07. After these 5 years, you
will have paid a total sum of 6000, of which 700.93
were used just to cover the interests. 

Example
3: If you take Example 1 and additionally enter
an optional prepay of 30 per month, you will see that
in the end you have saved 9 month of repaying, and
compared to Example 1 only needed 1117.1 instead of
1332.74 to cover the interests.

Savings Calculator
Use the Finance Calculator to see how much you have to save
to retire a millionaire.
 To calculate how much you have to pay each month to end
up with a desired fund, enter your desired total amount,
the interest rate and the number of years you plan for reaching
your goal.
 To calculate how much money you will own after regular
monthly payments, enter your monthly payment, the current
interest rate and the number of years you plan for saving.
 Press the
button to see the results.
 Interpreting the results:
Since there is no special savings mode, you' get the same
numbers as for the loan calculation, but have to interpret
the results differently:
The upper part sums up
your parameters: the total sum you have saved (Attention:
IGNORE this sum if you have entered monthly payments!),
the time over which you save, the interestrate and
the monthly payments. The lower part of the table
shows how much you have payed and how much interests
you gathered for your money.

Example
1: If your desired savings are a total of 10000,
and you want to reach this sum in only 5 years, having
an interest rate of 5% means that you'll have to pay
188.71 per month. After these 5 years, you will have
saved a total sum of 11322.74, of which 1332.74 are
the interests you gained. 

Example
2: If you want to save 100 monthly over 5 years,
having an interest rate of 5% means that you will
posses 6700.93 after this period  your total payments
of 6000 plus the interests of 700.93. 

Thus, to figure out how much you have to save to be a millionaire
when you retire, just enter 1 million as the total amount,
the interest rates you get, and the number of years you
have left until retirement  and the monthly rate will tell
you how much you have to carry to the bank each month to
reach that goal.

Tip Calculator
The Tip Calculator offers a unique locationbased tip calculation:
 The appropriate tip amount is calculated based on your
current whereabouts and your satisfaction.
 You also get extra information per country about which
tip is expected for taxis or whether the hotel or restaurant
bill already includes the service charge.
 You can easily split the bill between the people in your
group.
How to
calculate the tip:
 Selecting your whereabouts from the Country list will
display information about customary tipping amounts for
that country. This countryspecific amount will be the basis
for the tip calculation.
 Selecting the satisfaction will automatically adjust the
tip percentage.
 Of course, you can also set a custom tip amount by entering
it into the "Tip" field or by using the
adjecent spin buttons.
 Enter the "Bill" amount in corresponding
field to have the Tip and Total calculated.
To split the bill among a group of people, just enter the
number of people in the "No People" field,
and the sum per person is displayed below.
