Yes, there is an exponential Excel function (or EXP function) that is used to return a numeric value to e raised to the power of a given number or cell and it is often used with the LOG function. Here, e is the exponential constant (the base of natural logarithm) and its value is equal to 2.71 approximately. The EXP function syntax is written as EXP(number). So, let's say you want to determine the constant e to the power of value present in cell A3, then the EXP function formula is =EXP(A3).
