Welcome to DN CALC!

This is a powerful scientific calculator designed to handle a wide range of mathematical calculations. Here's a quick guide to its functions.

Basic Operations

Use the number keys (0-9), decimal point (.), and arithmetic operators (+, -, ×, ÷) for basic calculations. Press = to see the result.

You can also use your keyboard: press Delete or Escape for All Clear, and Backspace to delete the last character.

Angle Units (Deg/Rad)

Select 'Deg' for degrees or 'Rad' for radians using the radio buttons. This affects trigonometric functions.

Scientific Functions

• x², x³: Square and cube a number.
• xʸ, ʸ√x: Raise a number to a power or find the nth root.
• √x, ³√x: Square root and cube root.
• 1/x: Find the reciprocal (1/x).
• n!: Calculate the factorial of a number.
• sin, cos, tan: Trigonometric functions.
• sin⁻¹, cos⁻¹, tan⁻¹: Inverse trigonometric functions.
• log, ln: Base-10 and natural logarithms.
• 10ˣ, eˣ: Exponential functions.
• EXP: Used for scientific notation (e.g., 1.23 EXP 5 is 1.23 x 10^5).
• %: Immediately converts the current number to its decimal equivalent (e.g., 50 becomes 0.5).
• ±: Change sign of the current number.
• RND: Rounds the current number.

Constants & Memory

• π, e: Insert the constants Pi or Euler's number.
• Ans: Recalls the last calculated answer for use in a new calculation.
• M+: Adds the current display value to memory.
• M-: Subtracts the current display value from memory.
• MR: Recalls the value from memory to the display.

Enjoy calculating!
