The natural logarithm is the logarithm to the base e, where e is approximately equal to 2.71828... (no exact fraction can be given, as e is an irrational number just like pi). The natural logarithm is defined for all positive real numbers. Although this function was not introduced by Napier, it is sometimes known as the Napierian logarithm.
