xFunc

xFunc is a lightweight, portable application that can lend you a hand with creating complex mathematical expressions which will be automatically computed.

Since the app is portable, you can drop the program files somewhere on the hard drive and just click the executable to run. The application is as easy to use as it looks, meaning that it comes with a fresh and intuitive interface that is unlikely to give you any troubles.

The GUI is a single, clean window where you can use standard, trigonometric, hyperbolic, bitwise, constants, numbers and arithmetic, along with additional tools to write expressions. You can create logic expressions, graphs and truth tables.

Expressions and answers can be copied to the Clipboard or input. In case you make a mistake or change your mind, don’t fret. It is possible to undo and redo your actions, select the answer base (e.g. binary, decimal, hexadecimal), add variables and functions, as well as clear the expression list.

As far as settings are concerned, you can ask the tool to remember the last window state and position, right toolbar state, number base and angle measurement, as well as specify the maximum number of expressions.

At the same time, you can configure the maximum number of expressions to be displayed in the interface via the Settings. Moreover, if your expressions can be expressed as graphs, you can customize the color of the chart. Here you can use the default color palette, create your own or use a hex number, which can come in handy for those doing homework or an assignment for instance. Needless to say that the tool is suitable for both students and teachers alike.

XFunc comes packed with resourceful options dedicated to computing mathematical expressions, and it should please everyone.
