CALC ULUS is an application that originally came out for Mac. Many changes later, including several add-ons such as the Native Calc Server, have made it a robust calculator with Windows side integration. It's free and available for download. It was one of the very first calculator tools that was able to export figures in vector format (so this tool is also a vectorizer). This is handy as some programs don't export in the common bitmap format (and can be very confusing).
While in the standard mode, this calculator is similar to the classic calculator with a few extra features. In its programmer mode, the application allows the user to enter a few simple data types, such as the square root of a number, the maximum value for a floating point number, the average value of a number, and the real estate sales volume for city in which the numbers were calculated. In addition to these data types, this program also allows the user to enter formulas, enter dates and times, create tabs, copy and paste data, and undo calculations. While in programmer mode, the application allows the user to enter arbitrary numeric data.
The final version of the CALC ULUS software included a graphing capability, along with basic calculator and scientific calculator widgets, in addition to the ability to export figures. Though the final release of the software didn't have a graphing capability built-in, it comes included with a graphing widget that allows the user to draw graphs and graphical representations of the numerical results. As mentioned above, this calculator is very much like the classic calculator, with the exception that it offers Windows interface functions that may not be included on earlier versions. To sum it up, this is an excellent calculator that is perfect for anyone who needs to perform a wide range of basic, complex, and logical mathematical calculations.
