# How To Do E In Excel

Are you a programmer, mathematician, or a data analyst struggling to calculate the mathematical constant ‘e’ in Excel? Well, you are not alone and this blog post is for you. Let’s dive right into it!

## Understanding ‘e’

The number ‘e’ is a famous irrational number, and is one of the most important numbers in mathematics. It is often defined as the base of the natural logarithm and it approximately equals to 2.718281828459. You might come across this constant if you are dealing with problems related to growth and decay, compounding interest, or even in more complex topics like calculus.

## Calculating ‘e’ in Excel

While there isn’t a built-in formula in Excel to calculate ‘e’ directly, we can use the EXP function which stands for ‘exponential’. The EXP function in Excel returns the constant e raised to the power of a number. Therefore, to get the constant e itself, we just raise e to the power of 1.

Here’s how you can do it:

```=EXP(1)
```

After typing this formula into a cell and hitting enter, Excel will return the constant ‘e’ up to 15 decimal places, which is 2.71828182845904.

```=EXP(n)
