Antilog

Definition

The antilog, also known as the inverse logarithm, is a mathematical operation that reverses the process of taking the logarithm of a number. It is used to find the original number from its logarithmic value, and is particularly relevant in the context of biological acids and the Henderson-Hasselbalch equation.
