Screen Shots
These screen shots were taken from computers running the Windows Vista and Windows XP SP2 operating systems, and are shown at their actual size.
UltimaCalc Main Window
The first two actual-size images (on Windows XP) show UltimaCalc at its narrowest width, and with the window's title bar removed. With no title bar, the window can still be dragged, by clicking and dragging on the area to the right of the menus. The third image (on Windows Vista) shows the main window at a width great enough to show results to full precision. These three windows show the font at its largest setting. Notice that the background colour can be changed.

Multiple Results
Some calculations generate more than one result. When this happens, UltimaCalc can show all of the results together in a separate window. The screen shot below shows various fractions which approximate the value of pi. The button marked 'Copy' will copy the displayed text to the Windows clipboard so that it can be pasted into any program that accepts plain text.
Non-linear Least Squares Fit
UltimaCalc can fit an arbitrary expression to a set of data. The following image shows a typical calculation. Assuming that each X-Y pair can be represented by the equation y=a+b*(1-exp(-x/c))2, the question is, "What are the values of the variables a, b and c which give the best fit?" To answer this, we need to start from a set of (guessed) initial values.
Options
UltimaCalc has a wide range of options available. The following screen shot shows the window for specifying the format to be used for displaying numbers in the main window. Click on the image for more information. For the full range of options, consult the manual and use the 'Next' and 'Prev' links to navigate.)
