About this app

Don't let the simple interface fool you, this calculator is packed with features. Beautiful rendering of both the question and answer make your calculations virtually foolproof. Built in symbolic manipulation gives you the mathematically perfect answer to most common computations, with a fall back on 64 bit floating point approximations to handle the nastiest math. Supports integer calculations in binary, decimal, and hexadecimal for byte, word, dword, and qword integers. Calculate one and two variable statistics with four available regression models. Macros make it easy to repeat calculations without any programming skills.

This app is exactly what I need in physics. HOWEVER, it is missing one important function. Yes, the app can be forced to convert a fraction into a floating point decimal. However it cannot do it the other way around. In otherwords if I type in 3.2 the calculator returns 3.2 and not 16/5. It would be great if the app had a button that could toggle between fractions and decimals.

If you switch to the Ultimate or Ultimate 2 layout (available on our website), you can rationalize numbers by long-pressing the "round" toolbar button. Put the number to rationalize in the y register and the maximum denominator in the x register.

Don't walk, run to get this app. I teach a math intensive short course to a lot of people who used to hate math. I recommend this app to my students. They love it and say how simple it makes the most complicated math. It shows you every step and is very intuitive. It holds your hand all the way through your calculation. Please consider a financial version one day. Thanks for a great app.

Check out the Ultimate 2 layout from our website. It provides TVM financial functions when you long-press the 5 button.

Perfect except I would like a version for a tablet that is scalable and always on top. Very nice app!
