What is the Ln Function?

The natural logarithm, represented as ln(x), is the logarithm to the base e, where e is an irrational constant approximately equal to 2.71828. Natural logarithms are widely used in mathematics, physics, computer science, and finance to model exponential growth, decay, and other complex phenomena.

The formula is simple: ln(x)=yifey=x\text{ln}(x) = y \quad \text{if} \quad e^y = xln(x)=yifey=x

For instance:

ln(1) = 0 because e^0 = 1
ln(e) = 1 because e^1 = e

With this online Ln Calculator, you don’t need to memorize formulas or perform manual calculations.
