Euler’s number is a mathematical constant with a value of approximately 2.71828. The number itself goes on indefinitely without any repeating patterns, much like the mathematical concept of pi. A Swiss mathematician in the 18th century named Leonhard Euler studied it and determined the value.
This function represents a number of interesting properties that make it useful in Excel. It serves as the base for natural logarithms in mathematics and is commonly used to calculate compound interest or to model growth or decay over time.
