List of representations of e
The mathematical constant "e" can be represented in a variety of ways as a real number.
 Since "e" is an irrational number (see proof that e is irrational), it cannot be represented as the quotient of two integers, but it can be represented as a continued fraction.
 Using calculus, "e" may also be represented as an infinite series, infinite product, or other sort of limit of a sequence.
