2e6

2e6 is a numeric literal written in scientific notation, where the “e” denotes exponent. It represents 2 × 10^6, which equals 2,000,000. This compact form is common in calculators, programming languages, and scientific data to express large or small numbers without long strings of digits.

In practice, 2e6 is read as “two times ten to the sixth” or simply “two million.” It is not a unit but a value expressed in decimal form. In computing and data contexts, the meaning of 2e6 can depend on how quantities are labeled. If used to denote bytes without binary prefixes, 2e6 bytes equals 2,000,000 bytes, approximately 1.91 mebibytes (MiB). When contrasted with decimal megabytes (MB) and mebibytes (MiB), 1 MB is defined as 1,000,000 bytes, while 1 MiB is 1,048,576 bytes.

As a floating-point literal, 2e6 is a valid constant in many programming languages, interpreted as the floating-point value 2000000.0. It is favored for its readability when dealing with large scales, data sizes, or scientific measurements. The notation is also used in spreadsheets and data files, providing a concise way to convey substantial quantities without sacrificing precision in the exponent.

Overall, 2e6 serves as a standard shorthand in mathematics, science, and computing for the value two million, expressed in scientific notation for clarity and compactness.
