Papertape Calculator keeps a record of every entry made by the user. It displays, on a "papertape", all of the entries made in a calculation and saves the user time since a review of the papertape is all that is needed to check one's work. Re-entry of the data is not required.
It also simplifies several otherwise complex calculations such as mean, median, mode, variance, standard deviation, root mean square, linear least squares regression and multiple regression.
This calculator updates the relevant data as each data point entry is made. This shows the user how each data point contributes to the final result.
The calculator also offers the user a variety of pre-programmed calculations for lines, planes, quadratic and cubic equations, bessel functions, loan and amortization calculations and annuities.
Here are some key features of "xPapertape Calculator":
· Papertape records all data entries and operations. Text entries to papertape are also possible. All entered data and operations are archived.
· Data entered can be saved for later use.
· Sections of papertape can be saved for user's records. Last saved papertape can be recalled for additional use.
· Individual numerical entries on the papertape can be double clicked to the display for further use in calculations.
· Compound interest calculations.
· Simplified linear least squares regression analysis
· Simplified multiple regression analysis which allows use of dummy variable.
· Multi-function calculator that allows for running calculations.
· Parenthesis function allow for user control of order of operation execution.
· Trigonometric functions.
· Conversion calculations.
· Constants.
· 10 memory locations with window that displays memory contents.
· Currency format for basic functions.
· Detailed instructions and documentation.
· Use of constant functionality.
· Percent calculations.
· Calculations of on line and plane.
