🔢 Radix Converter User Guide

The EVEDAYS Radix Converter is a free web tool for quick and intuitive number base conversions commonly needed in programming, network configuration, and hardware development. Supported bases: • Binary (BIN, base 2): The fundamental unit for all data representation inside computers. Consists only of 0s and 1s. • Octal (OCT, base 8): Primarily used in Unix/Linux file permissions (chmod 755, etc.). • Decimal (DEC, base 10): The number system we use in everyday life. • Hexadecimal (HEX, base 16): Widely used in memory addresses, color codes (#FF5733), MAC addresses, and more. Additional features: • Bit Visualization: Displays the converted binary number bit by bit, allowing intuitive verification of each bit's ON/OFF state. • Click to Copy: Click any conversion result to instantly copy it to clipboard. • 4-bit Grouping: Binary numbers are automatically grouped in 4-bit units for improved readability.

📊 Basic Conversion Principles

Example of converting decimal 255 to other bases: • 255(10) → Binary: 11111111 255 = 1×2⁷ + 1×2⁶ + 1×2⁵ + 1×2⁴ + 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 • 255(10) → Octal: 377 255 ÷ 8 = 31 remainder 7 → 31 ÷ 8 = 3 remainder 7 → 3 ÷ 8 = 0 remainder 3 • 255(10) → Hex: FF 255 ÷ 16 = 15 remainder 15(F) → 15 ÷ 16 = 0 remainder 15(F) In hex: A=10, B=11, C=12, D=13, E=14, F=15.

💡 FAQ

Q. Is there a limit on the input number size? A. Conversions are accurate up to JavaScript's integer precision (approximately 2^53 - 1). This is sufficient for general use. Q. Can I convert negative numbers? A. Negative numbers are only supported for decimal input. Binary/Octal/Hex results are displayed as unsigned 32-bit integers. Q. Does case matter in hexadecimal? A. Input accepts both uppercase and lowercase. Output is displayed in uppercase (A-F) for readability. Q. Do I need to enter prefixes like 0b or 0x? A. No. Since you specify the input base with the selection buttons, just enter the digits without any prefix.
