Decimal to Hexadecimal Converter

Decimal to hexadecimal conversion is a fundamental concept in computer science and digital systems. Our Decimal to Hexadecimal Converter tool provides an efficient solution for converting decimal numbers to their hexadecimal equivalents, supporting both integer and floating-point numbers. This guide explores the conversion process, features, and practical applications of our tool.

What is Hexadecimal?

Hexadecimal is a base-16 number system that uses sixteen digits (0-9 and A-F) to represent numbers. It provides a more concise way to represent binary data, where each hexadecimal digit represents exactly four binary digits (bits). This makes it particularly useful in computer programming, memory addresses, and color codes.

The Mathematics Behind Decimal to Hexadecimal Conversion

Decimal to Hexadecimal Mapping

Decimal │ Hex Decimal │ Hex 0 │ 0 8 │ 8 1 │ 1 9 │ 9 2 │ 2 10 │ A 3 │ 3 11 │ B 4 │ 4 12 │ C 5 │ 5 13 │ D 6 │ 6 14 │ E 7 │ 7 15 │ F

Conversion Process

1. Divide the decimal number by 16 repeatedly
2. Keep track of remainders in reverse order
3. Convert remainders greater than 9 to letters A-F
4. Handle decimal points through multiplication method

Integer part: 2023 = 7E7 2023 ÷ 16 = 126 remainder 7 (7) 126 ÷ 16 = 7 remainder 14 (E) 7 ÷ 16 = 0 remainder 7 (7) Decimal part: 0.75 = C 0.75 × 16 = 12.0 (C)
