Frequently Asked Questions
What logarithm bases are supported?
The tool supports base 10 (common log), base e (natural log, ln), base 2 (binary log), and any custom positive base.
What is the natural logarithm?
The natural logarithm (ln) uses base e (approximately 2.71828), the mathematical constant.
Can it calculate antilogarithms?
Yes. The tool can compute the inverse of logarithm: if log_b(x) = y, then b^y = x.
