Hexadecimal is a base-16 number system commonly used in programming for its concise representation of binary values. Converting various data types to hexadecimal format can be particularly useful in scenarios like memory addressing, color representation, and data serialization. In this article, we will explore how to convert different data types to hexadecimal in Kotlin, complete with practical examples. Understanding Hexadecimal Hexadecimal (often abbreviated as hex) uses sixteen symbols: 0-9 represent values zero to nine, and A-F represent values ten to fifteen. This representation allows for more compact notation compared to binary (base-2) or decimal (base-10) systems. For example, the decimal number 255 is represented as FF in hexadecimal.
