For example, how would I go about entering the value e^2 in R?

### 3 Answers

The R expression

```
exp(1)
```

represents e, and

```
exp(2)
```

represents e^2.

This works because `exp`

is the exponentiation function with base e.

`-digamma(1)`

is the **Euler’s Constant** in R.

`e`

, (`exp(1)`

in R), which is the *natural base of the natural logarithm*

if you want to have a little number `e`

to play with, you can also make one yourself:

```
emake <- function(){
options("warn"=-1)
e <- 0
for (n in 0:2000){
e <- e+ 1/(factorial(n))
}
return(e)
}
e <- emake()
e^10
exp(10)
# or even:
e <- sum(1/factorial(0:100))
```

fun stuff
