0x1

0x1 is a common hexadecimal literal used in programming and data representations. The 0x prefix signals that the following digits are in base 16; in 0x1, the digit is 1, so the value equals decimal 1 (binary 1). Hex notation uses digits 0–9 and letters a–f (case-insensitive).

In source code, 0x1 appears as a literal assigned to variables or used in expressions. For example,

Common uses include bit masks and flags, where 0x1 often represents the least-significant bit (bit 0). For

In the context of blockchain and networks, 0x1 is sometimes used to denote the Ethereum mainnet chain

Fundamentally, 0x1 is not a separate number type; it is a textual representation of the integer 1
