Scientific Calculator Classic

Scientific Calculator Classic brings the feel of a real school & engineering calculator to your phone – the same keys, the same two-line LCD display and the same order of operations you use in class and in exams. ★ EVERYTHING A STUDENT OR ENGINEER NEEDS • Trigonometry: sin, cos, tan and their inverses in Degrees, Radians or Grads • Hyperbolic functions: sinh, cosh, tanh and inverses (hyp key) • Logarithms & powers: log, ln, 10ˣ, eˣ, x², x³, xʸ, √, ∛, ˣ√, x⁻¹ • Fractions: enter a b/c, get exact fraction answers, switch to decimal or improper fraction (d/c) • Degrees–minutes–seconds (° ′ ″) input and conversion • Factorial x!, permutations nPr and combinations nCr • Polar ↔ rectangular coordinates: Pol( and Rec( • Percent calculations: 200 + 10% = 220 • Engineering notation (ENG) and scientific E-notation (EXP) • Random numbers (Ran#), π and e constants, absolute value and rounding ★ WORKS LIKE A REAL CALCULATOR • Natural algebraic order: 1 ÷ 2π, -2², 2sin(30) all give the right answer • Two-line display shows your full expression above the result • Edit anywhere with the cursor, insert or overwrite (INS) • REPLAY ▲▼ – scroll back through previous calculations and edit them • Ans key and automatic "Ans" when you continue from a result • Variables A, B, C, D, E, F, X, Y and independent memory M (M+, M−, STO, RCL) • Display modes: Fix (0–9 decimals), Sci (1–10 digits), Norm 1/2 • Clear error messages (Math ERROR, Syntax ERROR) – press ◀ ▶ to jump straight to the mistake ★ ACCURATE Decimal arithmetic means 0.1 + 0.2 = 0.3, sin 180° = 0 and 1 ÷ 3 × 3 = 1 – no strange floating-point answers. ★ MADE FOR YOU • Beautiful classic design with a realistic LCD and 3D keys • Haptic key feedback and press-and-hold repeat for DEL and the cursor • Your history, variables and settings are saved automatically • Small, fast and works offline • Supports hardware keyboards Perfect for high school, college and university students, engineering, physics, chemistry and maths homework, exam practice, and anyone who prefers a classic scientific calculator to a plain phone calculator.
