# Scientific Calculator_ A full expression calculator: trigonometry in degrees, radians or gradians, inverse and hyperbolic functions (via **2nd** / **hyp**), logs, powers, roots, factorial, constants, memory, last-answer recall, and a running history. Type with the keypad or your keyboard. ## Notes The calculator parses a full expression with correct precedence — `2 + 3 × 4 = 14`, powers are right-associative (`2^3^2 = 512`), and implicit multiplication works (`2π`, `3sin(30)`). Switch the angle unit with the **DEG/RAD/GRAD** key; it applies to `sin/cos/tan` and their inverses. **2nd** turns the trig keys into `sin⁻¹` etc. and `ln/log/log₂` into `eˣ/10ˣ/2ˣ`; **hyp** gives `sinh`, and **2nd+hyp** gives `sinh⁻¹`. `%` divides by 100, `n!` uses the gamma function so it also accepts non-integers, and `Ans` recalls the last result. Keyboard: digits, `+ − * / ^ ( ) % !`, **Enter** = equals, **Backspace**, **Esc** = clear. ## Accessibility ### Screen reader support --- *Source: [ocxly.com/scientific-cal.html](https://ocxly.com/scientific-cal.html) — OCXLY, free 100% client-side privacy-first tools.
