ABOUT Eval calculator
An advanced scientific calculator with support for complex numbers and fractions. Also check out Plottron, with 2D/3D function, 2D/3D parametric, and 2D polar graphing. 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.
