0x26259FF

0x26259FF is a hexadecimal literal used in computing to denote a numeric value. The prefix 0x indicates hexadecimal notation in many programming languages, such as C, C++, JavaScript, Python, and Solidity. The literal contains seven hex digits, which encodes a 28-bit value without leading zeros.

In decimal form, 0x26259FF equals 39,999,999. This conversion is straightforward by expanding the hex digits: 0x2 6 2 5 9 F F corresponds to 2×16^6 + 6×16^5 + 2×16^4 + 5×16^3 + 9×16^2 + 15×16 + 15 = 39,999,999.

Because the value is seven hex digits, it is not a standard-length Ethereum address, which requires 40 hex characters after 0x. It is more commonly encountered as a constant in code, for example as a memory offset, a bitfield mask in a 28-bit space, or a sample numeric value in tutorials illustrating hex arithmetic. Its limited length makes it convenient for demonstrations, tests, or educational examples.

In practice, 0x26259FF serves mostly as an example of hex notation; it does not, by itself, designate a widely standardized identifier. In software engineering documentation, it may appear in snippets to illustrate conversions, ranges, or comparisons.
