🔍 What Is a Scientific Calculator Casio?

A scientific calculator is a digital device or online tool used to perform complex mathematical, trigonometric, exponential, and logarithmic calculations beyond the scope of a regular calculator.
Our Scientific Calculator Casio replicates the layout and functionality of traditional Casio fx-series calculators, providing a familiar and intuitive experience for Irish students, accountants, engineers, and teachers.

This online calculator supports:

• Arithmetic operations (+, −, ×, ÷, %)

• Powers and roots (x², √, ^)

• Trigonometric & inverse functions (sin, cos, tan, asin, acos, atan)

• Logarithmic & exponential (log, ln, e, π)

• Factorial (!)

• Parentheses and order of operations

• Keyboard input and calculation history

🔬 How the Calculator Works

The Scientific Calculator Casio uses JavaScript-based mathematical logic that mimics how Casio calculators process input.
It interprets mathematical expressions in real time, applies order of operations (BODMAS), and uses built-in Math functions for high precision.

Key features include:

• Automatic function mapping (sin(x) → Math.sin(x))

• Factorial calculations up to 170!

• Percentage and exponent conversion

• History tracking using your browser’s temporary memory

The logic ensures fast, accurate, and safe computation — entirely within your browser, without sending any data to external servers.
