Longhand

Longhand is an application that allows users to perform basic as well as complex mathematical calculations.

The utility has a friendly and simple to use interface divided into panels for the input values and output results. Longhand supports the use of constants and functions and is completely free.

The application has the look and feel of a text editor as there are no digit buttons. This and the support for brackets make it considerably more intuitive to use. Output is available in a choice of base: 10 floating point, 10 scientific, 10 integer, 10 fractions, 8 fractions, 2 fractions, 16 fractions. Users can specify the number of decimals displayed, select the fonts for the calculator and transcript panels. A sound notification will trigger each time a calculation is completed (which may be disabled from the program Preferences).

The utility comes with a few built-in declarations for constants and functions, which are stored in a specific file. You can always add more functions by editing the file.

In summary, Longhand makes for a flexible and powerful solution for performing mathematical calculations.
