Scientific Calculator Documentation

What is a Scientific Calculator?

A scientific calculator is a powerful online calculation tool that supports basic operations and advanced scientific computing functions. It provides trigonometric functions, logarithmic functions, exponential operations, power operations, and other scientific calculation features, suitable for students, engineers, researchers, and others who need to perform complex mathematical calculations.

Main Features

Basic Operations: Supports addition, subtraction, multiplication, division and other basic mathematical operations

Scientific Functions: Provides trigonometric functions (sin, cos, tan), inverse trigonometric functions, logarithmic functions, etc.

Exponential Operations: Supports power operations, squares, cubes, roots, etc.

Angle Modes: Supports degree (Deg) and radian (Rad) mode switching

Memory Functions: Provides M+, M-, MR, MC and other memory operations

Keyboard Support: Supports keyboard input for improved efficiency

Constants: Built-in π (pi) and e (natural constant)

Basic Operations

Click the [number keys]/[function keys] on the web calculator to perform calculations
You can also use number keys and symbols like "+ – × ÷ , . =" on your keyboard for calculations
The "Backspace" key on your keyboard can delete the last input
The "Enter" key on your keyboard is equivalent to "=" and will perform calculations directly

Function Key Descriptions

AC

Clear the numbers in the display area or perform clear constant operation

M+

Add the display number to memory number, calculate result and store in memory

M-

Subtract the display number from memory number, calculate result and store in memory

MR

Display the number stored in memory to the screen

MC

Clear the content stored in memory

Rad

Switch to radian mode (used for trigonometric/inverse trigonometric calculations)

Deg

Switch to degree mode

RND

Output a random number greater than 0 and less than 1

Frequently Asked Questions

How to switch between degree and radian modes?

Click the "Deg" or "Rad" button on the calculator. Deg means degree mode (0-360 degrees), Rad means radian mode (0-2π).

How to use memory functions?

M+: Add the currently displayed number to memory; M-: Subtract the currently displayed number from memory; MR: Display the number in memory; MC: Clear memory.

What keyboard shortcuts are supported?

Supports number keys 0-9, operators +, -, *, /, Enter (equals), Backspace (delete), decimal point, etc.

How to calculate trigonometric functions?

First select degree mode (Deg) or radian mode (Rad), then enter the angle value, and click the corresponding trigonometric function button (sin, cos, tan).

Can complex numbers be calculated?

The current version does not support complex number calculations, only real number operations.

What is the calculation precision?

The calculation precision depends on JavaScript's floating-point precision, usually 15-17 significant digits.
