The **`fegetround()` function** gets the floating-point rounding direction, or the current environment's mode of rounding.

# Library
```c
#include<fenv.h>
```

# Declaration
The following is the declaration of `fegetround()`:
```c
int fegetround();
```
This function does not take any parameters.

# Modes of rounding
The four modes of possible rounding that can be returned are:
## 1. FE_TONEAREST
In this mode, the floating point value is *rounded* to the nearest integer.

## 2. FE_DOWNWARD
In this mode, the function returns *floor* of the floating-point value.

## 3. FE_UPWARD
In this mode, the function returns *ceil* of the floating-point value.

## 4. FE_TOWARDZERO
In this mode, the function returns the integer that is *closer to zero* of the floating-point value.


> Note: The default mode of rounding is `FE_TONEAREST`.

# Code
The code below illustrates the use of `fegetround()`. 

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

int main()
{
    printf("%ld", lrint(-0.7));    //rounding off the number
    if (fegetround() == FE_TONEAREST) {
        printf("\nfegetround() = FE_TONEAREST\n");
    }
    
    fesetround(FE_DOWNWARD);
    printf("\n%ld", lrint(1.8));    //calculating floor of number
    if (fegetround() == FE_DOWNWARD) {
        printf("\nfegetround() = FE_DOWNWARD\n");
    }
    
    fesetround(FE_UPWARD);  
    printf("\n%ld", lrint(1.2));    //calculating ceil of number
    if (fegetround() == FE_UPWARD) {
        printf("\nfegetround() = FE_TOUPWARD\n");
    }
    
    fesetround(FE_TOWARDZERO);
    printf("\n%ld", lrint(0.8));    //return number closer to zero
    if (fegetround() == FE_TOWARDZERO) {
        printf("\nfegetround() = FE_TOWARDZERO\n");
    }
    
    return 0;
}

In this code, the modes are set using `fesetround()`. The functionality of `fegetround()` is then verified using an *if* statement.

What is fegetround() in C?

fegetround() in C retrieves the current environment’s floating-point rounding mode: FE_TONEAREST, FE_DOWNWARD, FE_UPWARD, or FE_TOWARDZERO.
