Scientific Calculator
Advanced precision mathematical calculator with trigonometry, logarithms, powers, roots, constants, and calculation history.
Executes trigonometric functions (sin, cos, tan), logarithms, powers, roots, and factorials locally on your device with complete confidentiality.
The FileTools Scientific Calculator provides a comprehensive mathematical workspace for engineering, physics, calculus, and financial calculations directly in your browser. Unlike basic desktop calculators limited to simple arithmetic, this tool evaluates complex mathematical expressions with proper operator precedence, handles trigonometric computations in Degrees, Radians, or Gradians, supports exponential and logarithmic analysis, and maintains an interactive calculation history with memory registers.
Key Challenges Solved
- ✓ Bypass file upload size caps and process your scientific calculator tasks directly in browser RAM.
- ✓ Works instantly in your browser without requiring desktop software installation or admin rights.
- ✓ Zero data leakage guarantee—files are processed locally and never stored on remote servers.

Important Operational Notes & Realistic Limitations
- Standard factorial (n!) is defined for non-negative integers; evaluating factorials for decimals or negatives displays a domain error.
- Dividing by zero or computing the logarithm of non-positive numbers displays standard mathematical infinity or domain error indicators.
- Computations exceeding JavaScript numeric limits (approx. 1.8 × 10³⁰⁸) will evaluate to Infinity.

Frequently Asked Questions
What is the difference between DEG, RAD, and GRAD angle modes?
DEG (Degrees) divides a circle into 360 units. RAD (Radians) measures angles based on arc length (2π rad = 360°), standard in calculus. GRAD (Gradians) divides a circle into 400 units, common in surveying.
How does the Ans button work?
Clicking "Ans" inserts the result of your immediately preceding calculation into your current active formula.
Can I use my computer keyboard to type calculations?
Yes. The calculator fully supports physical keyboard input, including numbers, arithmetic operators (+, -, *, /), parentheses, and Enter to evaluate.
Is my calculation history saved when I close the browser?
The calculation history is maintained in temporary browser memory during your active session and resets when the page is refreshed.
What advanced scientific functions are supported?
Trigonometric functions (sin, cos, tan, radians/degrees), logarithms (log, ln), powers, roots, factorials, and constants (pi, e).
Does the calculator follow standard operator precedence (PEMDAS)?
Yes. Expressions are evaluated strictly according to mathematical order of operations.
