What Is a Log Calculator?
A log calculator is a specialized tool—either a physical device or software—designed to compute logarithms. It can handle common logarithms (base 10), natural logarithms (base e), and logarithms with custom bases. These calculators are essential for students, engineers, and scientists who need to solve logarithmic equations, analyze exponential growth and decay, and work with functions in fields like finance, physics, and computer science. The best log calculators not only provide answers but also help users understand the underlying principles of logarithmic functions.
