0x125F

0x125F is a hexadecimal literal used in computing to denote the integer value 4703. The prefix 0x signals that the digits following it are in base 16, a common convention in many programming languages for writing numeric constants.

In decimal, 0x125F equals 4703. In binary, it is 0001 0010 0101 1111, which fits into 16 bits (two bytes). The compact four-digit form is often used for short offsets, bit masks, or small addresses in systems with 16-bit addressing or constrained registers. Because it represents a fixed bit pattern, 0x125F is frequently involved in bitwise operations such as AND, OR, and XOR to manipulate specific bits.

Contexts and usage. 0x125F may appear as a constant in source code to denote an address, offset, flag, or mask, particularly in low-level programming, embedded systems, or debugging. Its exact meaning depends on the surrounding architecture, language, and data model. It is not a universal identifier on its own but a literal that must be interpreted within a given context.

Notes and distinctions. In contrast to 0x125F, Ethereum addresses require 40 hexadecimal characters after 0x and thus are much longer; 0x125F would not be a valid address in that environment. Hex literals like 0x125F are distinct from color codes used in web design, which typically appear as six- or three-digit hex values without the 0x prefix.
