Eval (v. 2.2) Разработано NIXON |
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.

[2012-02-09] A Google User: Almost 5 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. |

[2011-03-24] A Google User: 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. |
