0x193F

0x193F is a hexadecimal literal used in computing to denote the integer value 6463. In hexadecimal notation, the 0x prefix signals base-16, and 0x193F equals 1×16^3 + 9×16^2 + 3×16^1 + 15×16^0, which is 6463 in decimal. This form is widely used across programming languages such as C, C++, Java, JavaScript, and Python to initialize constants, define bit masks, and reference memory addresses or registers in hardware-related code.

In practice, the meaning of 0x193F is context-dependent. As a numeric constant, it can participate in arithmetic or bitwise operations. As a memory address or register identifier in a 16-bit address space, it designates a location within a device's map. In graphics or embedded systems, it can also serve as a color-related value or a control parameter, depending on the width and interpretation of the data.

Because the prefix and value are unambiguous by themselves, 0x193F is a standard example of a hexadecimal literal, illustrating how hex values encode decimal numbers and how they integrate into source code and hardware specifications. The practical interpretation of 0x193F thus relies on the surrounding context, including the language, data type, and hardware architecture involved.
