23e2

23e2 is a representation of a numeric value using scientific notation, where the letter “e” denotes “times ten raised to the power of.” In this format, 23e2 corresponds to 23 × 10², which equals 2 300. Scientific notation is commonly employed in mathematics, engineering, physics, and computer science to express very large or very small numbers in a compact and readable form.

In computing, the “e” notation is standard in many programming languages and data formats, such as C, Java, Python, JSON, and CSV files. It allows developers to input floating‑point numbers without explicitly writing the exponentiation operator. For example, the literal 23e2 in code is parsed as a double‑precision floating‑point value of 2300.0. The notation also supports negative exponents; for instance, 5e‑3 represents 5 × 10⁻³, or 0.005.

The use of scientific notation dates back to the work of 16th‑century mathematicians, but the “e” form was popularized with the advent of electronic calculators and early computers, where the letter “e” could be typed easily on limited keyboards. Today, the format is integral to data interchange standards and scientific calculators, facilitating the concise communication of numerical results across disciplines.

In scientific literature, 23e2 may appear in tables, graphs, or textual descriptions where space is limited and readability is essential. While the value itself—2,300—is straightforward, the notation emphasizes the magnitude's order of magnitude, an important concept when comparing quantities that differ by many powers of ten.
