High Precision Calculator

High Precision Calculator – a scientific calculator designed for high-precision decimal calculations and clear expression display.

This scientific calculator is built for people who need more than a basic calculator: students, engineering majors and anyone who works with numbers every day. Type a full expression with parentheses, powers, roots and trigonometric functions, and get a high-precision decimal result.

CORE CALCULATION FEATURES
• Four operations: addition, subtraction, multiplication and division
• Percentage and remainder calculations
• Square root, square, cube and custom powers (x^y)
• Factorial (x!) for supported integer values
• Reciprocal (1/x) function
• Logarithms: log base 10 (lg), natural log (ln) and custom base log
• Trigonometry: sine, cosine and tangent
• Inverse trigonometry: arcsin, arccos and arctan
• Degree and radian mode, with angle conversion
• Scientific constants: pi (π) and e
• Parentheses and operator precedence for combined operations
• Configurable decimal precision for high-precision results

A SCIENTIFIC CALCULATOR WITH HISTORY
Every calculation is stored in a history list, so you can review past expressions and results, reuse an earlier value, and keep your work organized. The history list is useful for math homework checking, exam preparation and step by step expression entry.

TWO KEYBOARDS IN ONE APP
Switch between a simple calculator keyboard and a scientific calculator keyboard with one tap. The simple layout covers daily arithmetic, while the scientific layout adds sin, cos, tan, lg, ln, x^y, x!, 1/x, π and e — a multi function scientific calculator in a single screen.

DESIGNED FOR REAL WORK
• Large buttons that are easy to press
• Clean interface that keeps the result readable
• Works offline, with no internet connection required
• Handles negative numbers, nested brackets and long decimal values

WHO IT IS FOR
• Scientific calculator for students and high school math
• Engineering calculator for Android devices
• Calculator for algebra, physics, chemistry and statistics homework
• Calculator for college and university math courses
• Calculator for daily math, accounting and percentage work

USEFUL CALCULATOR FEATURES
This high precision calculator combines the functions many users look for in a scientific calculator with history: square root and percentage calculations, sin cos tan, factorial and powers, degree and radian mode, inverse trigonometric functions, pi and e, decimal precision, parentheses and operator precedence.

It also works as a scientific calculator offline and a multi function scientific calculator for everyday calculations, study, homework and general numerical work.

Notes:

* Calculations use high-precision decimal math within the supported calculation range.
* Displayed digits depend on your chosen precision setting.
