We use the **`expl()` function** -- a variation of `exp()` -- to compute `e` raised to the power of `x` for `long double` in C.

# Library
```c++
#include<math.h>
```

# Syntax
Below is the declaration of the `expl()` function:
```c++
long double expl(long double x);
```
Here, `x` is a `long double` exponent passed as the parameter to the function.

The function returns `e` raised to the power of `x` as a `long double` value.

# Code


#include <math.h>
#include <stdio.h>

int main()
{
   long double var1;
   long double var2;
   var1 = 4.5;
   var2 = -1.3;
   printf("e^4.5 = %Lf", expl(var1));  //Calculates e^4.5
   printf("\ne^-1.3 = %Lf", expl(var2));  //Calculate e^-1.3
   return 0;
}
