0x7C0

0x7C0 is a hexadecimal numeral used in computing and digital systems to represent the integer value 1984. In decimal form, 0x7C0 equals 1984; in binary it can be shown as 0111 1100 0000 when padded to 12 bits. The 0x prefix is a common convention in many programming languages, such as C, C++, Java, and JavaScript, to denote hexadecimal literals.

Common uses and context

Hexadecimal values like 0x7C0 are widely employed to specify constants, memory addresses, offsets, and bit masks in low-level programming and hardware interfacing. For example, a program might use 0x7C0 as an offset from a base address or as part of a bitwise mask to preserve or clear particular bits. Because hexadecimal notation aligns neatly with binary representation, hex literals are convenient for inspecting and manipulating individual bits in registers or data words. Note that 0x7C0 and 0x07C0 denote the same value; leading zeros are a matter of formatting and do not change the numeric value.

Practical considerations

When assigning 0x7C0 to different integer types, its suitability depends on the target width. As 1984, it fits within 8-bit, 16-bit, and larger types, but would overflow an 8-bit unsigned interpretation if the language automatically restricts values to 0–255. In code, 0x7C0 is simply the numeric value 1984; its interpretation—address, mask, or constant—depends on the surrounding context, such as the data structure or hardware interface involved.
