The exponential constant is a mathematical constant with a value of roughly 2.718282..., usually denoted by the letter e.
2.
The related exponential function is ex (e to the power of x). The exponential function in Excel is =EXP( ). The exponential function is the inverse of the natural logarithm.
3.
Exponential growth means growth other than straight-line. For example the series 100, 200, 400... is growing exponentially.
4.
Exponential decay means the reduction in a variable, for example over time, on a basis other than straight-line. For example the reduction in the time value of an option, as its remaining time to maturity expires.
