Calculator³

VARIANTE
Calculator³ is a professional-grade 3-in-1 scientific, graphing and programmer calculator—lightweight and minimal, yet powerful without compromising functionality. Its intuitive UI makes this calculator fun and easy to use, and at its core it possesses many advanced features which common calculators overlook: RPN, gradian mode, decimal and negative non-integer factorials, modulo operator—just to name a few.

For FREE, Calculator³ comes loaded with:
- The feature-packed Scientific Calculator (you can toggle advanced functions in the in-app settings panel when in portrait mode)
- Today widget—perform simple math on your device lock screen
- Apple Watch app
- RPN mode

The Graphing Calculator and Programmer Calculator require IAP unlock, but comes with 3 trials each for you to give them a test run. During the trial periods you have access to all features. Simply reinstall the app to replenish the trial counts.

Graphing Calculator Highlights:
- This is like a TI calculator—you can perform calculations on a tape and plot graphs. The tape is smart enough such that you don't have to close parenthesis, you can multiply out brackets, and you get real-time syntax highlighting.
- Plotting mode uses adaptive sampling algorithm to generate precise results. At your fingertips you can choose to show/hide roots/intersections and trace the graphs.
- It also includes all functions in the Scientific Calculator.

Programmer Calculator Highlights:
- Supports 8, 16, 32, and 64-bit bitwise calculations.
- Binary (base-2), octal (base-8), decimal (base-10), and hexadecimal (base-16) numeral systems too.
- Unicode (UTF-16) and ASCII character encoding.
- A binary table that shows you in real time the binary representation of the current operand.
