About Eval (legacy)
Important Note:
Please upgrade to Eval (other listing).
An advanced scientific calculator with support for complex numbers and fractions. Free graphing calculator also available.
Features:
- Complex (imaginary) numbers (a+bi or polar form)
- Probability distribution functions (binomial, chi-square, Gaussian (normal), geometric, inverse Gaussian, Poisson, Student-T PDF)
- Cumulative PDFs (CDF)
- Numbers stored internally as fractions
- Mixed/improper fractions
- Function integrals and numerical derivatives
- Live Calculation: evaluate expressions as they are entered
- Trigonometric functions for complex numbers
- nCr and nPr (Combinations and permutations)
- Degrees, radians, or gradians
- Haptic feedback
- Unlimited expression history
- Physical and chemical constants
- User-defined variables
NOTES:
- To change the display mode (fraction, polar, etc.), click on an evaluation.
- To use internal fractions, press the Divide [÷] key instead of entering decimals. For example, press [1][÷][4] instead of 0.25.
- Improper fraction mode will display mixed fractions if they're approximated. It will only display improper fractions when they can be used internally.
- Decimals up to 5 places will be converted to internal fractions.
- For more information, go to Menu > Settings, then Help and Information or Enumeration of Functions.

I'm studying for my 3rd actuarial exam and I needed a quick normal and inverse normal calculator that isn't connected to the Internet so that I can focus and not goof off. I haven't played with the rest of the app yet but I did notice it would be nice to have a blinking cursor in the expression bar so you can easily change the equation, right now it's a little trial and error to be in the right spot.

Great app these are one of very few app that have the I function. Would love a+bi and graphing function. N1.

Good app. It's rare to find one with statistical distributions. I would like to see graphing functions added.

Great app. For those of you that want to use fraction mode, just tap the input line and it will switch between modes. Seems to drain my battery fast.

Satisfies my needs, but i'd like it to be able to restore history across restart and want to be able to choose symbols for multiplication/division and calculator/phone-style number key layout.

Nice looking interface, BUT... is it too much to ask to be able to position cursor INSIDE the expression, at any position? Back to Mobi calc.
