0x300

0x300 is a hexadecimal numeral representing the numeric value 768. The prefix 0x denotes hexadecimal notation in many programming languages such as C, C++, Java, and JavaScript, and is used to express constants, memory addresses, and bit flags.

As a value, 0x300 equals 768 in decimal. It commonly appears as a literal in source code to initialize variables, set configuration bits, or represent offsets and addresses in low-level programming.

In computing and hardware contexts, 0x300 is often encountered as a memory address or offset within a 1KB page or 4KB page, depending on the architecture. The interpretation depends on the addressing mode, endianness, and whether the value is used as an absolute address or an offset.

In Unicode, the hexadecimal code point 0x0300 corresponds to the combining grave accent. While 0x300 and 0x0300 are numerically equivalent, the leading zero is a typographical convention. The combining grave accent is used in many scripts to modify the preceding character.

Notes: Leading zeros are often omitted in hex literals, so 0x300 is commonly written without extra zeros. Endianness affects how a multi-byte hex value is stored in memory, but not its mathematical value.
