NCalc — Powerful Scientific Calculator, Graphing, and Converter

NCalc combines a natural-display scientific calculator, advanced maths tools, a full graphing module (as 83/84 calculator), a large formula library, and a comprehensive unit and currency converter—designed for students, engineers, and anyone who loves maths.

◉ Main Calculator Features
- Natural display: Enter expressions exactly as in textbooks—fractions, roots, exponents, and more—see results as written on paper.
- Keyboard layout: Matches popular models for familiarity and speed: 115 ES Plus, 991 ES Plus, 300 ES Plus, and 991 EX.
- Symbolic and numeric modes: Perform exact fraction calculations or evaluate numerically when needed.
- Arbitrary‑precision integers: Work with very large integers without losing accuracy.
- Output types: Choose from fraction, mixed fraction, decimal, recurring decimal, degrees/minutes/seconds, and polar coordinates.
- Angle units: Degree, radian, and gradian (grade).
- Decimal formatter: Display numbers in normal, engineering, engineering SI, scientific, or fixed formats.
- Calculation history: Review and reuse past calculations with ease.
- Copy and paste support for fast data entry and sharing.

◉ Algebra, Calculus, and Core Maths
- Algebra calculations: Expansion, factorisation, simplification, and more.
- Calculus calculator: Derivatives, integrals, and limits of expressions.
- Complex number calculations: Arithmetic, polar/rectangular conversion, exponential, logarithms, powers, roots, and full trigonometric functions.

◉ Equations and Inequalities
- Equation solver: Solve general equations, plus dedicated solvers for quadratic, cubic, and quartic equations.
- System of equations solver: Solve systems with 2, 3, or 4 variables.
- Inequality solvers: Quadratic, cubic, and quartic inequalities with interval‑based solutions.

◉ Matrices and Vectors
- Operations: Addition, subtraction, multiplication for matrices and vectors.
- Advanced tools: Determinant, inverse, transpose, rank, eigenvalues, and eigenvectors.

◉ Statistics and Distributions
- Statistical calculation: Descriptive stats and regression calculation (including a regression plotter).
- Distribution calculation: Normal distribution, binomial distribution, Poisson distribution, t‑distribution, chi‑squared distribution, and F‑distribution.

◉ Number Bases and Formats
- Base‑N calculation: Effortlessly switch between binary, octal, decimal, and hexadecimal, with arithmetic in each base.

◉ Tables, Variables, and Custom Functions
- Table Generator: Generate value tables based on any expression and range.
- Calculator variables: Store values and reuse them across calculations.
- User‑defined functions: Create your own functions to streamline repetitive work.

◉ Built‑ins and Help
- Built‑in constants: A rich set of mathematical and physical constants.
- Built‑in documentation: Access helpful guidance anytime via the Help button.

◉ Formulae
- Extensive formulae collection: Maths and Physics formulae, clearly categorised—ideal for secondary school, sixth form/college, and university students.

◉ Unit Converter
- Currency Converter: Up‑to‑date exchange rates for quick conversions.
- 1,000+ unit conversions: Length, mass, time, energy, power, temperature, pressure, data, and more—organised for fast lookup.
