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

Simply type in your calculation. You can go back and edit your 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.

Using the RES (Result) feature, you can link to the results of any number of past calculations in history in your calculation. If you go back and redo your calculations, the changes are automatically propagated down to all the affected calculations.

Use the Memory feature to save up to 20 items in memory. You can optionally provide convenient names for the stored values, for instance: "Sales Tax", or "Tip".
