natural logarithmic calculation

1. A natural logarithm is a logarithm with the constant e as its base. The general form of a natural logarithm is ln N (N > 0).

2. Natural logarithms play a significant role in the natural sciences; they are generally denoted as ln x, though in mathematics they are also commonly represented as log x.

3. The constant e represents the limit value reached by continuous doubling over a unit of time.

4. e is a non-repeating decimal with an infinite sequence; its value is approximately 2.718281828459…, and it is a transcendental number.
