Logarithm Calculator

A logarithm calculator is a powerful mathematical tool that helps you find the logarithm of any positive number with any specified base. The logarithm answers the question: "To what power must the base be raised to get the given number?"

For example, log₁₀(100) = 2 because 10² = 100. This calculator supports:

• Common Logarithm (log₁₀): Base 10, widely used in science and engineering
• Natural Logarithm (ln): Base e (≈2.718), essential in calculus and exponential growth
• Binary Logarithm (log₂): Base 2, important in computer science and information theory
• Custom Base: Any positive number except 1
