305e5

305e5 is a numeric literal encountered in mathematics and computing that uses scientific notation to express a large decimal value. The notation follows the form mantissa e exponent, where the e denotes multiplication by 10 raised to the specified power. Specifically, 305e5 equals 305 × 10^5, which equals 30,500,000. It is equivalent to the more common 3.05e7 notation (3.05 × 10^7).

In programming languages, a number written with an exponent part such as 305e5 is typically parsed as a floating-point value. The exact type (for example, float or double) and the precision depend on the language and the surrounding code. While 305e5 is a valid literal, many programmers prefer 3.05e7 for readability because it more clearly communicates 3.05 × 10^7.

Usage and interpretation notes include the following: 305e5 and 3.05e7 represent the same numerical value, so they are interchangeable from a mathematical standpoint. However, readability concerns and tool behavior may lead developers to favor the latter form. In spreadsheets and data formats that support scientific notation, a similar representation is common, often allowing both mantissas and exponents to be written with a capital E or a lowercase e.
