4E6

4E6 is most often encountered as a numeric notation that uses the letter E to indicate an exponent. In scientific notation, 4E6 means 4 times 10 to the sixth power, which equals 4,000,000. This form is common in data files, reports, and calculations. In programming languages and calculators, 4e6 (or 4E6) is treated as a floating-point literal representing 4000000.0. The uppercase and lowercase forms are usually interchangeable in this context.

Beyond pure mathematics, 4E6 can also serve as a product, model, or catalog code in various industries. In such cases it does not convey a mathematical value but identifies a specific item within a manufacturer’s inventory or a distributor’s range. Because these uses are domain-specific, the exact item or meaning depends on the context, such as the industry, supplier, or product line involved.

In practice, when encountering 4E6, readers should determine whether it is being used as a numerical value in scientific notation or as an alphanumeric designation. If the context is technical writing, data analysis, or software, it most likely denotes four million. If the context is procurement, engineering parts, or inventory, it may refer to a particular product code requiring additional context to interpret.
