Casio-inspired scientific keyboard: natural expression entry, angle modes, hyperbolic functions, logs, powers, memory, and Ans.
Last Updated: 20 Feb 2026
Keyboard: type numbers and operators (Enter or = evaluates, Esc clears, Backspace/Delete erase). Tab to this panel (outline) or click inside so keystrokes apply. Ctrl/⌘+V pastes if the text is valid for the expression. Use on-screen SHIFT / HYP for alternate legends. mod(a,b) uses a comma. Ans updates after =.
Online Calculator helps you casio-inspired scientific keyboard: natural expression entry, angle modes, hyperbolic functions, logs, powers, memory, and ans. It is commonly used by professionals, students, general users for online calculator, scientific calculator, engineering calculator.
Engineering Calculator in Your Browser
This interface mirrors the layout and workflow of high-end Casio scientific calculators: dual-line display, shift and hyperbolic layers, trigonometry with configurable angle units, logarithms, roots, powers, factorial, and multi-register memory.
What You Can Do
- Enter full expressions with parentheses and standard operator precedence
- Switch between **DEG**, **RAD**, and **GRAD** for trig and inverse trig
- Use **SHIFT** for inverse trig and alternate functions; **HYP** for sinh, cosh, tanh (and inverse hyperbolic when shifted)
- Store running totals with **M+**, **M−**, recall with **MR**, clear with **MC**
- Chain calculations with **Ans** after each evaluation
