Abstract:
A print controller includes a processor and a memory. When an instruction to execute a specific calculation function is received, the processor obtains a calculation result related to the specific calculation function. When an instruction to print is received, if the instruction to execute the specific calculation function has been received a plurality of times without printing the calculation result related to the specific calculation function, which was obtained when the instruction to execute the calculation function was received one or more times before the instruction received at a last time of the plurality of times, the processor causes a printing device to print the calculation result related to the specific calculation function, which was obtained when the instruction to execute the specific calculation function was received at the last time of the plurality of times.
Abstract:
A calculator includes: a plurality of numeric keys; a plurality of operation keys; a delimiter key; a memory; and a processor, wherein said processor is configured to: when a first numerical data having at least a first integer, a delimiter, and a second integer arranged in that order has been received, upon receiving a prescribed operation of one of said plurality of operation keys, registers said first integer in said memory as a first operand, and registers said second integer in said memory as a second operand; and registers in said memory a target-operand that has been inputted via an operation or operations of at least one of said plurality of numeric keys, and performs a prescribed arithmetic operation on said target-operand registered in said memory using a plurality of registered operands that include the registered first and second operands.
Abstract:
According to one embodiment, a calculation data printing apparatus includes a printer and a processor. The processor is configured to execute processes of inputting a plurality of calculation data in accordance with a user operation; causing the printer to print, as first print data, the plurality of calculation data, and calculation result data of the plurality of calculation data; changing at least one of the plurality of calculation data in accordance with a user operation; and causing the printer to print, as second print data, at least one calculation data including the changed calculation data and calculation result data of the plurality of calculation data at least one of which is changed, without printing at least one of the plurality of calculation data printed as the first print data.
Abstract:
A computing device includes a processor to perform a coefficient calculation control for (i) displaying a mathematical formula including a coefficient on a display unit, (ii) displaying the coefficient name, and (iii) receiving a coefficient value to calculate the mathematical formula; and a regression calculation control for storing numeric data sets of independent and dependent variables in a memory and calculating a value of a coefficient in a regression formula representing the relationship between the independent and dependent variables based on the numeric data sets. The coefficient calculation control performs a coefficient value displaying control for displaying the value of the coefficient in the regression formula calculated through the regression calculation control and performs a post-regression calculation control for using the regression formula as the mathematical formula to calculate the mathematical formula using the displayed coefficient value.
Abstract:
A graph display control apparatus includes a figure display control unit, a graph figure change unit, a coordinate value calculation unit and a figure prominent display control unit. The figure display control unit sets a coordinate system to a display unit and displays (i) a first graph figure and (ii) a coordinate axis or a second graph figure in the system. The graph figure change unit moves or transforms the first graph figure in the system in response to a user operation to change the first graph figure. The coordinate value calculation unit detects an intersection point of (i) the changed first graph figure and (ii) the coordinate axis or the second graph figure and calculates a coordinate value of the intersection point. The figure prominent display control unit prominently displays the changed first graph figure when the coordinate value is an integer.
Abstract:
An electronic device including a processor configured to execute a program stored in a memory, in which the processor executes input-screen display processing of causing a display to display an input screen, in order to accept input of data for a certain item, executes, when the input of the data for the certain item is accepted by a first method during display of the input screen, default-value setting processing of setting the data as a default value for the certain item, and executes data processing with the data, and executes, when the input of the data for the certain item is accepted by a second method during display of the input screen, default-value non-setting processing of not setting the data as the default value, and executes the data processing with the data.
Abstract:
A calculation apparatus in which a controlling unit performs a first storing process for storing a first value in a storing unit; a first displaying process for executing operation on a second value, using the first value to obtain and display a first and second output value on a displaying unit; a second displaying process for executing operation on a third value, using the first value to obtain and display a third and fourth output value on the displaying unit; a second storing process for adding the third output value to the first output value and the fourth output value to the second output value to obtain and store a first sum and a second sum in the storing unit; and a sum displaying process for displaying the first and second sum stored in the storing unit on the displaying unit in response to operation of the key unit.
Abstract:
An expression processing device of the present invention includes an input unit, a display and a processor. The processor is configured to perform following processes: inputting an expression in response to a user's operation on the input unit; detecting a plurality of variables included in the expression input by the input unit, among the plurality of variables which are usable in expressions; and outputting the input expression and variable values associated with the detected variables.
