NUMRIX Scientific ULTRA

Overview

Native Windows Application · Certified on Microsoft Store

NUMRIX Scientific ULTRA is an advanced, high-performance scientific and graphing calculator developed and published under ANFA TECHNOLOGY. Engineered for students, engineers, mathematicians, and scientists, NUMRIX combines the familiarity of classic hardware scientific calculators with the power, precision, and interactive visual graphing of modern computing.

100% Private & Offline-First

All mathematical calculations, equation solving, matrix operations, and graphing run entirely on your local machine. No calculation history or private data is ever collected, tracked, or sent to external servers.

🔢 Over 417+ Built-in Functions Trigonometric (DEG/RAD/GRA), hyperbolic, exponential, natural log (ln), common log (log₁₀), powers, roots, permutations (nPr), and combinations (nCr).

📐 Natural Mathematical Display View expressions with proper mathematical typography, natural fractions (S⇔D toggle), mixed numbers, radicals, and exact algebraic answers.

📈 Interactive 2D Graphing Engine Plot up to 6 simultaneous mathematical functions in real-time. Features coordinate tracing, standard and trigonometric view presets, mouse-wheel zoom, and multi-touch gestures (1-finger drag to pan, 2-finger pinch to zoom).

🔲 Advanced Matrix & Vector Math Create matrices up to 3×3 with instant determinant calculation, transposition, inversion, and matrix arithmetic.

∫ Equation & Calculus Solvers Solve linear systems, quadratic equations (with real and complex root support), and cubic polynomials. Calculate numerical definite integrals (∫) and derivatives (d/dx).

📊 Statistics & Linear Regression Calculate sample and population standard deviation, mean, sum of squares, and linear regression parameters (y = a + bx) with correlation coefficients.

💻 Base-N Programmer Mode Perform bitwise logic (AND, OR, XOR, NOT, NOR, XNOR) and base conversions between Decimal (DEC), Hexadecimal (HEX), Octal (OCT), and Binary (BIN).

⚛️ Physical Constants & Unit Conversion Access over 40 standard physical constants (speed of light, Planck constant, gravitational constant) and convert distance, mass, and temperature units.

⌨️ Keyboard & Touchscreen Optimization Zero-latency touch support for Windows laptops (Surface, 2-in-1s) alongside complete physical keyboard shortcuts (press Ctrl+, for the shortcut guide).
