We use the **`exp2l()` function** to compute `2` raised to the power of `x` for `long double` in C.

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

# Syntax
Below is the declaration of the `exp2l()` function. 

Here `x` is a `long double` exponent passed as the parameter to the function:

```c++
long double exp2l(long double x);
```
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 = 5.5;
   var2 = -2.3;
   printf("2^5.5 = %Lf", exp2l(var1));  //Calculates 2^5.5
   printf("\n2^-2.3 = %Lf", exp2l(var2));  //Calculate 2^-2.3
   return 0;
}
