EZ Engineering Calculator vs 计算器

A serious engineering calculator that opens ready to use, with nothing interrupting you. ENGINEERING MODE Five keypad pages, from everyday arithmetic to graduate maths: • Functions: x^y, square and cube roots, nth root, |x|, n!, e^x, ln, log, log2, mod, floor, ceil • Trigonometry: sin/cos/tan, inverse, hyperbolic and inverse hyperbolic, degrees or radians • Discrete: permutations nPr, combinations nCr, GCD, LCM, AND/OR/XOR/NOT, bit shifts • Analysis: series, products, derivative d/dx, definite integral, mean, median, standard deviation, variance • Constants: pi, tau, e, phi, plus 15 physical constants including the speed of light, the gravitational constant, Planck's constant and Avogadro's number Derivatives use central differences and integrals use adaptive Simpson quadrature, not lookup approximations. Bitwise work shows hexadecimal, octal and binary side by side, with two's complement for negative numbers. Memory keys M+, M-, MR, MC and cursor keys let you go back and edit a long expression instead of retyping it. Expressions honour parentheses and operator precedence, and the result previews as you type, so you rarely need the equals key. UNIT CONVERSION 224 units across 15 categories: length, weight, volume, area, speed, time, temperature, pressure, power, energy, data, density, angle, force and electricity. Temperature uses the correct formulas rather than a scaled ratio. CURRENCY CONVERSION 166 currencies, updated daily. See one amount in several currencies at once, and type an expression straight into the amount field. Rates are stored on the device, so it keeps working offline. WHAT THE PAID VERSION GIVES YOU • No advertising of any kind, and no in-app purchases • Opens directly into the calculator, in engineering mode ALSO • 20 languages, with number formatting that follows your region • Dark mode • No account, no sign-in Privacy: no personal data is collected, and what you type never leaves your device.
