What is a natural logarithm?

A natural logarithm (ln) is the logarithm to the base 'e', where 'e' is approximately 2.71828. It's the inverse of the exponential function e^x.

Why is the natural logarithm important?

The natural logarithm appears frequently in mathematics, physics, and engineering, especially in contexts involving exponential growth and decay, such as radioactive decay or compound interest.

What happens if I enter a negative number or zero?

The natural logarithm is undefined for negative numbers and zero. The calculator will return 'NaN' (Not-a-Number) in these cases.
