FormulaCalculator for Mac

FormulaCalculator for Mac offers users numerous advanced calculator features, including tools for finance, geometry, and unit conversions. It's not the most intuitive program we've ever used, but it's not a bad choice if you're looking for features beyond the offerings of Apple's native Calculator app.

FormulaCalculator's interface is fairly straightforward, with a number pad on the right and algebraic and trigonometric functions on the left. A drop-down menu lets users select the finance, geometry, or unit conversion libraries; once one of these is selected, an additional drawer slides out to the right displaying additional features. The finance library includes calculations for annuity loans, savings, and compound interest, while the geometry library contains tools for calculating sides and angles and the area, volume, and circumference of objects. The conversion and constants library lets users access a variety of length, volume, weight, and temperature conversions and also contains math and physics constants. It took a little bit of experimentation for us to get comfortable with FormulaCalculator; switching between features resulted in error messages until we got into the habit of clearing our previous work and entering things in the correct order. The program comes with a fairly comprehensive Help file that explains its various features. Overall, we think FormulaCalculator is a good option for users who are seeking a free calculator that offers advanced tools in a variety of different areas.

FormulaCalculator for Mac installs and uninstalls without issues.

Developer's Description

FormulaCalculator is a great calculator application that allows you to perform basic operations, but also provides support for dealing with complex formulas. FormulaCalculator comes with 48 already defined formulas and 74 unit converters: The formula library covers formulas in the area of Finance, Geometry and some other commonly used formulas. It has developed into a more advanced desktop calculator that should fit engineers, students, and people working in the finance sector. It easily replace the standard desktop calculator that came with your system. The idea was to create a calculator with a familiar user-interface that looks like an ordinary calculator, but then have more advanced functions to those who need covered in side-drawers that are not visible by default. I have baked in a formula library, where a lot of standard formulas are defined as functions. Functions that are easy to use, and give the expected result. To make the functions easier to use, I have made a "request parameter model" that asks for the parameters in plain English. Thus, the user does not need to remember the details, or look up details another place. For those who need details about how the function calculate the result, it can be found in the log window when you press "=".
