### APP description

The logarithm with the constant e as the base is called the natural logarithm and is denoted by lnN(N>0).

It means the limit that can be achieved by continuous doubling of growth per unit of time.

The base e of the natural logarithm is given by an important limit. We define: $$lim(1+1/x)^x=e$$ when the x region is infinite.

e is an infinite non-cyclical fraction whose value is approximately equal to 2.718281828..., which is a transcendental number.
