4e3

4e3 is a numeric representation used in scientific notation to denote the value 4 times 10 to the power of 3, which equals 4000. It is commonly used to express large or precise numbers concisely in mathematics, science, engineering, and computing.

In programming and data formats, 4e3 is typically read as a floating-point literal. The lowercase or uppercase letter “e” (or “E”) signals the exponent part, indicating multiplication by 10 raised to that exponent. The value is usually treated as a floating-point number (for example, double or float), depending on the language and context. Other examples include 4e-3 (0.004) and 1.23e4 (12,300).

Advantages of this notation include compactness and ease of use in calculations and data entry, particularly for very large or very small numbers. It also helps avoid miscounting zeros in long decimals. Some languages require a decimal point or a leading digit to disambiguate integers from floating-point literals, but 4e3 is widely accepted as a valid float across many programming languages, including Python, JavaScript, C, and Java.

In summary, 4e3 is a standard scientific notation form meaning 4000, frequently appearing in code, data files, and mathematical notation as a concise way to express numerical values.
