FormulaCalculator for MacOSX

There are a few Formula Calculators for MacOSX. This one falls into the category of Financial/Scientific/Math calculators. It is a hybrid type of Formula Calculator that both accepts formulas in an edit window, but also have ordinary calculator buttons that give immediate answers while entering keystrokes. In the later case, the user builds his formula that he/she can edit later.
The main difference between a Formula Calculator and a button operated calculator, is that a Formula Calculator let you enter formulas, as a string of text that is evaluated. A button operated calculator executes the functions while you enter your formula, and only show the answer as you go. For a quick answer to a simple formula, a button calc is ok. For more comprehensive calculations, a formula calculator is better as it put your focus on the formula itself, and let you edit mistakes. A hybrid type lets you do both.
This calculator has various drawers that contain some of the advanced functions. This includes a left-drawer with variables, three right-drawers with library functions: Financial, Geometric, and Converters and constants. A bottom drawer opens for library functions to provide help for the selected function.
The calculator generate documentation that is aimed to improve workflow for those who write scientific papers or reports. The log receives documentation of functions used, as to what formulas and parameters is used to solve the equation. This text can be pasted into and edited to fit into a document the user is writing.
Features
The calculator comes with a formula library that contains 48 formulas in the area of Finance and Geometry. It also has many unit converters for converting between units in the area of weight, length, volume and temperature. It also has constants that are user editable.
A general feature with most Formula Calculators is the ability to copy complete formulas with the answer into documents you write as opposed to button type of calculators where only the answer can be copied.
As the formula library functions are not standard well known functions, the log from FormulaCalculator also contains the formulas the function itself use to calculate.
What some calculators has, that lack in this program is a graphic display where formulas can be seen as an image. An example of others that have this is the Magic Number Machine (free) or the Equation calculator (commercial).
Some formula calculators also have a feature for defining your own variables. In this program, you can use 10 predefined variable names. An example of one who let you define variables freely is SpeedCrunch that also is available on windows and linux.
Future plans for the project
It is planned a feature where the user can create his own named functions. Those functions can be saved on XML files and exchanged, with other students or colleges to improve their workflow. Such formulas contain a name, description, definition of each parameter, and a series of formulas needed to solve the function. When defining such functions, they will be available in the same manner as the built in functions that came with the calculator. The web-site will be developed to hold a user-submit-able library of functions they want to share with others. Such sharing / browsing should be available from inside the calculator.
Licensing
It is supplied with a free licence.
