Frequently Asked Questions

What is the difference between ln and log?: The natural logarithm (ln) uses base e (~2.71828), while the common logarithm (log) typically uses base 10. In many scientific contexts, ln is preferred because of its mathematical properties.
Why is ln(1) equal to 0?: This follows from the definition of logarithms. By definition, ln(1) = x where e^x = 1. Since e^0 = 1, x must be 0.
Can I calculate ln of negative numbers?: No, the natural logarithm is only defined for positive real numbers. Attempting to calculate ln of a non-positive number will result in an error.
What is the inverse of the natural logarithm?: The inverse of the natural logarithm is the exponential function, e^x. This means that if ln(y) = x, then e^x = y.
How precise are the results from this calculator?: This calculator uses JavaScript's built-in Math.log() function, which provides approximately 15 decimal digits of precision for most inputs.
