0x1A25

0x1A25 is a hexadecimal numeral commonly used in computing to denote a fixed numeric value. The prefix 0x signals that the following digits are in base-16. The digits are 1, A, 2, and 5, which correspond to decimal values 1, 10, 2, and 5. As a 16-bit quantity, 0x1A25 represents the binary sequence 0001 1010 0010 0101 and the decimal number 6693. In practice, its meaning depends on context; it may be used as a numeric constant, an address, or a bit mask.

In programming languages that adopt C-style syntax, 0x1A25 is written as a hex literal. Its exact type (such as int, unsigned int, or long) is determined by the language rules and any surrounding suffixes. In Python, JavaScript, Java, and C/C++, 0x1A25 evaluates to the integer 6693, regardless of the specific language's signedness, though interpretations for overflow or sign may differ in certain contexts. The value can be transformed into other representations, such as decimal, binary, or hexadecimal, for display or comparison operations.

Common uses for hex literals like 0x1A25 include defining constants in source code, specifying memory addresses or register locations in low-level programming, and performing bitwise operations such as masking or shifting. For example, in bitwise operations, a programmer might apply a mask like 0x1F to extract the lower five bits of 0x1A25, or compare it against another constant in control logic. There is no single canonical meaning for 0x1A25 beyond its role as a hexadecimal numeric literal, and its specific interpretation is determined entirely by its usage in a given program or document.
