The **`expf()` function** -- a variation of `exp()` -- computes `e` raised to the power of `x` for floating-point exponents in C.


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

# Syntax
Below is the declaration of the `expf()` function, where `x` is the floating-point exponent passed as a parameter to the function:

```c++
float expf(float x);
```
The function returns `e` raised to the power of `x` as a `float` value.

# Code


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

int main()
{
   float x;
   float y;
   x = 10.3;
   y = -2.5;
   printf("e^10.3 = %f", expf(x));  //Calculates e^10.3
   printf("\ne^-3.2 = %f", expf(y));  //Calculate e^-3.2
   return 0;
}

What is expf() in C?

Computes e to the power of a float exponent in C, returning a float.
