The mathematical constant, e, is the constant value (approx. equal to 2.71828182845904), for which the derivative of the function e^{x} is equal to e.
The Exponential Function (written exp(x)) is therefore the function e^{x}.
The Exponential Function is shown in the chart below :
The Excel EXP function calculates the value of the mathematical constant e, raised to the power of a given number.
The format of the function is :
where the number argument is a positive or negative real number that you want to raise e to the power of.
