0x117F

0x117F is a hexadecimal numeric literal commonly encountered in computing. Its value in decimal is 4479. In binary it is 0001 0001 0111 1111, which corresponds to 4,096 plus 256 plus 127 plus 15, yielding 4,479.

In terms of data width, 0x117F fits within 16 bits and represents the unsigned value 4479. If stored in memory on a little-endian system as a 16-bit quantity, the two bytes would appear in memory as 0x7F followed by 0x11. The interpretation of the value—whether as a plain number, an address offset, a bit mask, or some other meaning—depends on the surrounding code and data type.

Usage context: Hex literals like 0x117F appear in source code across many languages that adopt the 0x prefix to denote hexadecimal notation (for example, C, C++, Java, JavaScript, Python). The actual type of the value (int, unsigned int, long, etc.) is determined by the language rules and the surrounding expression or explicit type specification. Such literals are commonly used for low-level programming tasks, including defining constants, setting flags via bitwise operations, or specifying memory addresses or offsets at a hardware interface level.

Cautions: When assigning 0x117F to a narrower type (such as an 8-bit byte), truncation or overflow may occur depending on language rules and casting. Always consider the target width and signedness to avoid unintended results in arithmetic or comparisons.
