1-Calc, the only calculator you'll ever need: works like your favorite calculator. It supports 4 different calculator "modes", meaning it can behave like 4 different calculators depending on the settings (R.P.N., Algebraic, D.A.L. & Chain (simple)). You may either use your fingers or the stylus to press the onscreen buttons and start calculating right away. Use the green menu button in the upper left corner of the screen to gain access to the menu, from here you can change button groups, enter the options screen or exit 1-Calc. You may also use the directional pad on your Pocket PC to scroll through button groups by pressing up or down. Only button groups currently selected in the "Groups" tab of the Options screen will be accessible from the menu or via the up down buttons. The Groups tab is only available on the full version of 1-Calc.
Please note, this document is written assuming you are using the default skin that came with 1-Calc. If you are using a different skin and are unfamiliar with the operation of 1-Calc, it is recommended that you first select the default skin before further reading. To do so, press the menu button, usually located in the upper left of 1-Calc and press "Options". From the options screen, press the arrow facing right in the upper right corner of the skin until the tab labeled "Skins" appears, press on that Tab. From this screen you should see one or more skin names displayed, select "default" and then press the "ok" button in the upper right corner of the screen.
The currency converter will convert between over 80 different currencies.
When viewing the Currency Converter, you will see 2 display areas and 2 additional blue buttons below the menu button. The top display will show the amount you have entered using the numerical buttons on the calculator. The lower display, will convert the amount you added as you entered numbers to another currency. To change the currency you are converting from, press the upper blue button, this will display a list of currencies with there 3 letter abbreviations shown in brackets to the left of the name. You may switch which display area to enter values into by tapping on the screen in the display area. Values will be entered on the display area that is lighter in color. When changing to other calculator screens, the value in the lighter area will be carried on.
To change the currency you are converting to, press the lower blue button and select a new currency.
The 1-Calc Currency Converter will always show the 3 letter abbreviation for the currently selected currencies on each display. It will also automatically change the currency symbol for the selected currency.
You may do basic calculations while using the Currency Converter by using the +, -, x, ÷, +/- and = buttons.
For more information on the Currency Converter, please see the Currency Converter Options section.
The unit converter can be displayed by selecting "Unit Converter" from the 1-Calc menu. If you cannot see the unit converter, you'll need to select it from the Groups Tab Page under options.
When viewing the Unit Converter, you will see 3 display areas and 3 additional buttons, 2 below the menu button, and one to the right. The top display will show the type of conversions being done. The middle display will show the values entered using the numerical buttons on the calculator. The bottom display will converter the amount you've entered in the middle display.
To change the type of conversions, press the blue button to the right of the menu button and to the left of the top display area. You will see a list of conversion types, press on a conversion type to choose a new one. The Unit Converter supports the following conversions: Distance, Temperature, Speed, Computers, Area, Energy, Power, Mass, Force, Pressure, Clothing. You may switch which display area to enter values into by tapping on the screen in the display area. Values will be entered on the display area that is lighter in color. When changing to other calculator screens, the value in the lighter area will be carried on.
To change the units of the the value you are converting from, press the blue button directly below the menu button and select a new measurement. The abbreviation for the currently selected measurement will show at the top of the middle display.
To change the units of the value you are converting to, press the lower blue button. The abbreviation for the currently selected measurement will show at the top of the lower display.
When choosing Clothing Conversions, a new page will display allowing easy conversions between US, UK, European and Japanese clothing sizes for many common clothing articles. To change the clothing conversion type or to change the sizes, press the down arrows. Press the OK button when finished.
You may do basic calculations while using the Unit Converter by using the plus, minus, times, divide, plus/minus and equals buttons.
The bill amount should be entered using the number buttons at the bottom of 1-Calc. By pressing on the two down arrow buttons, the percentage of the tip and the number of people to split the bill can be changed. The Tip Calculator will display the Total Tip and the total amount per person.

Notation
This controls the way 1-Calc handles large and small values displayed onscreen. Change the notation style by selecting a different option in the notation section.
Standard - is the default, this will use exponents if the calculated answer is smaller that 0.0001 or 1e-4. It will also use exponents if the calculated answer is 1000000000 ( 1.0e10) or larger.
Scientific - will select Scientific notation. Exponents will always be used for numbers less than 1 or equal to 10 or greater. Numbers between 1 and 10 will not display the exponent portion as the exponent will be equal to zero.
Fixed - will select fixed notation. Fixed notation will not display answers using exponents until the answer exceeds the calculators display accuracy of 12 significant figures. It will use exponents for numbers less than 0.000000001 (1.0e-9). Like Standard , it will use exponents for numbers equal to and greater than 1000000000 ( 1.0e10).
Engineering - will select Engineering notation. It operates much like Scientific notation except that exponents will always be represented in powers of 3. For example. Scientific Notation will represent 10000 as 1e4, Engineering Notation will represent it as 10e3. For numbers greater than 1 and less than 1000, no exponent will be shown as the exponent value will be zero.
*Please note, the above mentioned tolerances refer to the absolute value of an answer and not just the positive representation. For example, Standard, & Fixed will use exponents for numbers larger than 1.0e10 or less than -1.0e10.
Calculator Mode
1-Calc can operate in 4 different calculator modes:
Algebraic - behaves like a basic scientific calculator
D.A.L. - Direct Algebraic Entry, behaves like an advanced direct input scientific calculator. Some functions can be entered before entering the values
R.P.N - Reverse Polish Notation
Chain (Simple) - Works like a simple handheld calculator. This is the same setting 1-Calc version 1.x used
R.P.N. Stack Size
The stack size can for R.P.N. mode can be adjusted between a 3, 4, and 12 layer stack. This only affects 1-Calc in R.P.N. Calculator mode.
Repeated Equals
When 1-Calc is in Chain (simple) mode, the equals key can be pressed repeatedly after a calculation to repeat the previous calculation.
