- functions for computer programmers: And, Or and Xor
- statistical functions, including linear regression
- complex numbers
- hexadecimal, binary and octal support
- variables
- creating function plots
- zooming and panning
- full screen function plots
- saving an image of a function plot
- cursor
- syntax checking

The results screen is fully interactive. Tapping on an expression displays the keyboard for that expression. Function plots allow panning and zooming, and double tapping for full screen viewing. An image of a function plot can be saved to the camera roll.

Quintile Math is available for just a fraction of the price of a physical calculator.

Enjoy!

Note: In answer to some of the reviewers: the calculations *are* correct. Remember that the trigonometric functions are in radians, not degrees.
