2e3

2e3 is a numeric expression written in scientific notation, representing the value 2 multiplied by 10 to the third power. In other words, 2e3 equals 2000. The letter "e" is used to denote the exponent of base 10, so it expresses powers of ten in a compact form.

In scientific notation, the exponent can be positive or negative. For example, 2e3 = 2000, while 2e-3 = 0.002. This notation is common in science, engineering, mathematics, and various data formats where large or small numbers need to be represented succinctly.

In programming and data contexts, 2e3 is typically a floating-point literal. Many languages interpret it as a number of type float or double rather than an integer. For instance, Python treats 2e3 as 2000.0, JavaScript treats it as 2000, and C/C++ treats it as a floating-point value (usually double) unless a suffix is used to change the type. The exact handling can depend on the language and compiler, but the value corresponds to 2 × 10^3.

In written form, 2e3 can also be displayed as 2e+03 in some outputs, or written out in full as 2 × 10^3 or 2000. It is important to note that this notation uses the letter "e" to denote exponent base 10 and is not related to the mathematical constant e (approximately 2.71828).

Applications of this notation include compact representation of data in spreadsheets, scientific calculations, and code where readability and range are important. See also: scientific notation, floating-point literals, exponential notation.
