KoolCalc is a simple scientific calculator for devices using the WindowCE operating system for PocketPC 2002 or newer. Its user interface resembles the layout of standard scientific calculators like e.g. the TI-30, TI-34 or other devices from Texas Instruments or HP. While providing the most common features of a scientific calculator, care was taken to keep it lightweight, easy to use and not to overload it with unnecessary features.
The display area is the topmost area of the calculator. It shows one numerical value (the calculation result or the value being entered) with a precision of more than 20 digits in either floating point, fixed point (2 decimals) or scientific (mantissa + exponent) format.
Only one value is displayed at a time but by clicking or tapping into the display area a dropdown listbox is opened showing all previous calculation results. From this results log a value can be selected which is transferred to the display area as operand for the next operation. The results log can be closed without selecting a value simply by clicking into the display area again.
The mode buttons are located directly beneath the display area and can be used to switch between different display or operation modes. The mode buttons cycle through all available modes by clicking on them.
First Button Position represents the display mode for values:
| [Flt] | ... | Floating Point e.g. '1.23423423', '234234.2342' |
| [Fix] | ... | Fixed Point (2 decimals) e.g. '12313.12' |
| [Sci] | ... | Scientific (mantissa + exponent) e.g. '3.12541234124e-5' |
Second Button position represents the switch for the units used in functions taking angle values as operands:
| [Deg] | ... | Degrees 0 - 360 |
| [Rad] | ... | Radians 0 - 6.28 (=2*PI) |
The keypad is used to enter values and perform operations.
| [0] to [9] | ... | used to enter a numerical value |
| [.] | ... | used to enter the decimal point, the decimal point can be entered only once for a value |
| [+/-] | ... | changes the sign of the value, toggles between positive and negative value |
| [EE] | ... | switches to scientific format while editing a value and allows to edit the exponent of the value |
| [+] | ... | the addition operator |
| [-] | ... | the subtraction operator |
| [*] | ... | the multiplication operator |
| [/] | ... | the division operator |
| [mod] | ... | performs a modulo operation, this is like a division but results in the remainder of the division |
| [1/x] | ... | calculates the reciprocal value |
| [(], [)] | ... | used to group subcalculations, any level of subcalculations is possible |
| [CE] | ... | removes the last digit entered |
| [C] | ... | resets the currently displayed value to 0 and clears any pending operation |
| [Inv] | ... | Inverts the functionality of the function buttons, every function button performs a specific function, if [Inv] is pressed ever button perferoms the inverse of the basic function |
| [sin], [asin] | ... | calculates the sine of the given angle value, the inverse function is the arc-sine |
| [cos], [acos] | ... | calculates the cosine of the given angle value, the inverse function is the arc-cosine |
| [tan], [atan[ | ... | calculates the tangens of the given angle value, the inverse function is the arc-tangens |
| [log], [10^x] | ... | calculates the logarithm with base 10, the inverse is the 10th exponent |
| [lb], [2^x] | ... | calculates the logarithm with base 2, the inverse is the binary exponent |
| [ln], [exp] | ... | calculates the logarith with base e, the inverse is the e to the power of the given value |
| [x2], [√x] | ... | calculates the square of the given value, the inverse is the square root |
| [x^y], [y√x] | ... | calculates the y-th power of x, the inverse is the y-th root of x |
| [CArea],[CDiam] | ... | calculates the area of a cycle given its diameter, the inverse is the calculation of the diameter given its area |
| PI | ... | the value 3,1415...... |
Allows to display general information, open the menu, display contact or support information, etc.
Provides the options to switch between two different numerical keypad layouts.
| Mobile Keypad | ... | Displays the number buttons in the order typically found at mobile phones. User more familiar with mobile phones and writing SMS may find this layout more convenient. |
| Calculator Keypad | ... | Displays the number buttons in the order typicall found at pocket calculators. |
