258e4

258e4 is a string that may refer to several distinct concepts depending on context. There is no single, widely recognized object or standard known simply as "258e4."

In numeric contexts, 258e4 is commonly interpreted as a floating-point literal in scientific notation. It represents 258 × 10^4, which equals 2,580,000 (2.58 × 10^6). In many programming languages, writing 258e4 yields a numeric value of 2.58e6. By contrast, when written as a hexadecimal constant, people sometimes represent the same digits with a 0x prefix as 0x258E4, which equals 153,828 in decimal.

In practical use, the sequence may appear as a model number, part number, ticket code, or database key in various systems. In such cases the meaning is determined by the issuing organization and is not standardized.

Because 258e4 lacks a universal, unique meaning, access to additional context—such as the field, system, or source where the term appears—is necessary to identify the intended referent. See also references to hexadecimal notation and floating-point scientific notation for related concepts.
