UltimaCalc is a graphical calculator. Unlike most calculator programs, UltimaCalc
does not try to emulate a hand-held device. Its main window consists of just two
edit boxes. Enter an expression into one, hit the Enter key, and view the result in
the other edit box. The simplicity of the main window means that it can occupy
little screen area and thus be kept immediately available for use, staying on top of
other windows if you wish
Calculations are performed to a precision of over 38 digits, but you can choose to
limit the display to just 8, 12 or 16 digits, and view these in a variety of
formats. The \'engineering\' mode understands suffixes such as k (kilo) and M (mega),
and shows results using these suffixes, where possible. You can also view the
results in hexadecimal format, or have them approximated as various ratios.
UltimaCalc works with algebraic expressions and has all the standard functions
expected for a scientific calculator. Other functions find the slope of a line given
the coordinates of its end points, or calculate definite integrals. You can define
your own functions, too.
From the main window, you can open other windows for specialised calculations.
UltimaCalc has a comprehensive context-sensitive help system to explain how to use
these windows.
You can create bar charts, pie charts and stacked bar charts in 2D or 3D, line
charts or ribbon charts. Add a title, subtitle and legend. Choose colours and create
your own styles for hatching or cross-hatching (useful if you intend to photocopy
the results in black and white). Select the fonts you like and design your own
layout by dragging its elements around.
With the Regression window you can plot a scatter chart and show a least squares
regression line. Or you can fit a polynomial to your data. If the data depends on
more than one variable, you can tease out the effects of each variable. Try using an
absolute deviation fit to minimise the effect of outlying values.
You can plot functions. Specify the precise starting condition(s), the ending
condition(s), and how the variables are to change at each step. Specify the
locations of the axes if the automatic settings are not appropriate. Show multiple
plots together.
The Standard Deviation window calculates the mean, median and standard deviation of
the entered data. Other windows solve Simultaneous Linear Equations, perform
Navigational calculations, or solve triangles: If you know the length of one side,
and two other sides or angles, UltimaCalc will calculate the remaining sides and
angles and display the triangle.
All graphs and charts can be saved as image files. Calculations can be copied to the
Windows clipboard as plain text and pasted into other applications. The calculations
done in the specialised windows can also be saved in data files, along with notes
about the calculation. Most such data files can be edited in Notepad.
UltimaCalc also works with dates. It can tell you the date of Easter in any year
since the Gregorian calendar started. It can calculate the date a certain number of
days or weeks from another date, or convert a date to a Julian day number.
