Abstract: An electronic device includes a touch-sensitive display screen to display a graphical representation of a mathematical relationship and to enable a user to enter a one-dimensional touch gesture thereon for performing a one-dimensional adjustment function for the displayed graphical representation. A display adjustment module interprets the one-dimensional touch gesture and performs the one-dimensional adjustment function. The display adjustment module performs a one-dimensional zoom adjustment function in response to one of a one-dimensional pinch touch gesture and a one-dimensional spread touch gesture. The one-dimensional zoom adjustment function increases or reduces a displayed range of values in a first dimension while maintaining unchanged a displayed range of values in a second dimension of the displayed graphical representation.

Abstract: The present subject matter relates to verifying functionality restrictions of a computing device. In an example implementation, the verification includes generating a notification message based on a verification code received in the computing device and status of a configuration mode in the computing device. When the status of the configuration mode is active, at least one functionality of the computing device is restricted. The configuration mode can be activated in the computing device by execution of a configuration file. The generated notification message is provided, which enables verifying that the at least one functionality of the computing device is restricted.

Abstract: To perform a binary-coded decimal (BCD) calculation, a processor receives values on which the BCD calculation is to be performed. A carry resulting from the BCD calculation is stored in a flag register of the processor, and the carry stored in the flag register is used to compute a result of the BCD calculation.

Abstract: A system comprises a processor and a keyboard coupled to the processor. The keyboard comprises a mathematical function key and an arrow key. When the mathematical function key is pressed, the processor causes the display to display a sequence of math functions or math menu choices upon a user repeatedly pressing the arrow key. For each math function displayed on the display, the processor concurrently also causes the result of the math function to be displayed without the user pressing another key.

Abstract: Systems, methods, and other embodiments associated with selection pointers are described. One example computer-implemented method includes generating and displaying a pointer on a display screen. The pointer is formed with a selection area defined by multiple pixels that are adjacent to each other and intersect at a common point. In response to a selection event, a location of the common point of the pointer on the display screen is determined and a value is returned from a graphical object on which the pointer is displayed. The value is determined from the location of the common point of the pointer.

Abstract: A method of converting a number to a binary representation based on a processor word size is described. In accordance with the method, a predetermined size segment of a number is converted to a binary representation wherein the predetermined size segment is based on the processor word size. Also described is a method of converting a number represented in binary form and comprised of more than one segment, wherein the segment size is determined based on processor word size, to a decimal representation. A first decimal segment resulting from converting a segment of the more than one binary segments to decimal form is combined with a second decimal segment resulting from converting another segment of the more than one binary segments to decimal form.

Abstract: A system, method, and computer-readable medium having instructions for determining a key press from a current keyboard state at a current time is described. The system stores signals indicative of a last key press, a last key press time, and a last keyboard state. The system determines released keys and pressed keys on the keyboard at the current time based on comparison with the last keyboard state. The system determines a key press at the current time if the first determination determines a single key press and if either of: (a) a match exists between the determined key press and the last key pressed and if the elapsed time between the current time and the last key press time is larger than a preset bounce time; and (b) a match does not exist between the determined key press and the last key press.
