25e3

25e3 is a numeric representation used in scientific notation. It denotes 25 × 10^3, which equals 25,000. The "e" stands for exponent and indicates the power of ten; the value is the same as 2.5 × 10^4. In decimal form, this is 25000.

Used widely in science, engineering, computing, and data formats, it allows large numbers to be written compactly. For example, measurements, data values, or software settings may be expressed as 25e3. It is common to see 2.5e4 as well, and both expressions refer to the same value.

In programming and calculators, 25e3 is typically parsed as a floating-point literal representing 25000 (often with a trailing .0 in some contexts). The exact interpretation can depend on the language or tool, but the underlying meaning remains consistent: twenty-five times ten to the third power.

Notes and related concepts: the notation is base-10 scientific notation and is distinct from notations that use binary prefixes or other bases. The symbol e here is not Euler's number; it is a shorthand for the exponent in base-10 notation. See also scientific notation and exponential notation for broader context.
