  1. Maths. The exponential constant is a mathematical constant with a value of roughly 2.718, usually designated by the letter e.
  2. Maths. 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. Statistics. Exponential growth means growth other than straight-line. For example the series 100, 200, 400... is growing exponentially.
  4. Statistics. 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.
