Maven Calculator is a powerful, quick and easy-to-use all-purpose calculator, designed for real-world mathematical calculations.

Simply type in your calculation. View a history of your past calculations. History saves your 20 most recent calculations.

In addition to performing basic arithmetic operations (+, -, *, /), you can also use nested brackets. You can also set the number of decimal places for your results (0 - 8). Calculate using one of four rounding modes: 0.5 and higher: up (default), always up, 0.5 and lower: down, always down.

Note that this version is for trial use only and has some limited functionality. Unlike the full version, it does not allow editing history, and the following features are disabled: M (Memory), MR (Memory Recall), RES (Result), CP (Copy/Paste).
