Store description excerpt
VantaCalc is a fast, reliable scientific calculator built as a solo project, designed for users who want precision, clarity, and smooth performance. Every function is arranged for minimal friction, whether you're doing quick everyday calculations or working through advanced expressions. Core Features • Scientific Calculator & Advanced Functions • Trigonometry (sin, cos, tan), inverse trigonometry (asin, acos, atan), and hyperbolic functions (sinh, cosh, tanh) with radian and degree mode toggles • Logarithms (log, ln), powers, roots, and exponentiation (^, sqrt, ^2, ^3) • Constants: high-precision pi and e • Percentage logic and full expression parsing with live preview • Smart Expression Engine & Custom Math • High‑precision decimal math architecture with adjustable precision controls (ranging from 0 to 28 digits) • Custom mathematical operations: Floor (floor()), Ceiling (ceil()), and Modulo (a mod b) • Logic and Truth Table support: Logical Implication (->), Equivalence (<->), propositional variable evaluation (p, q, r), and automated Truth Table generation • Variable assignment and dynamic tracking via CalculatorStateManager • Real‑time preview of results while typing with built-in error handling • Matrix Operations • Full matrix management including 3x3 matrix addition, subtraction, scalar multiplication, matrix multiplication, transposition, trace, determinant, and eigenvalues (via QR decomposition) • History Panel • Automatically saves all calculations with JSON persistence (CalculatorHistory.json) • Tap to reuse expressions or results • Multi‑select mode for exporting or clearing • Export history as text or as a clean PNG image • Memory Functions • M+, M–, MR, MC for multi‑step workflows with live visual indicators (M) • Extended Unit Converter & Base-N Engine • Categories: Time, Length, Weight, Temperature, Area, Volume, Speed, Pressure, Energy, and Power • Base-N Converter & Bitwise operations: Binary, Decimal, Hexadecimal, Octal radices, plus Bitwise NOT, AND, OR, XOR, and shift instructions • Clean, Minimal UI & Theme Management • Fast and responsive layout with dynamic multi-panel navigation and safe‑area aware layouts for modern devices • Built‑in dark and light themes utilizing customizable ThemeData scriptable objects and ThemeElement components • Offline Operation & Regulatory Compliance • All core features function entirely without an internet connection • Fully integrated Google Play Age Signals API architecture (v0.0.4) supporting dynamic regional tracking and child-protection runtime compliance parsing Future TargetsShort Term Targets • More constants (φ, τ, Avogadro, c, etc.)• Adjustable font size for accessibility • High‑contrast and custom theme variants Long Term Targets • Combinations and permutations (nCr, nPr) • Statistical functions (mean, median, standard deviation) • Single‑variable equation solver • Graph plotting (2D) • Symbolic differentiation and integration VantaCalc is crafted for students, profes
