# PetscSortReal
Sorts an array of `PetscReal` in place in increasing order. 
## Synopsis
```
#include "petscsys.h"  
PetscErrorCode PetscSortReal(PetscInt n, PetscReal v[])
```
Not Collective


## Input Parameters

- ***n  -*** number of values
- ***v  -*** array of doubles



## Note
This function serves as an alternative to `PetscRealSortSemiOrdered()`, and may perform faster especially if the array
is completely random. There are exceptions to this and so it is __highly__ recommended that the user benchmark their
code to see which routine is fastest.




## See Also
 `PetscRealSortSemiOrdered()`, `PetscSortInt()`, `PetscSortRealWithPermutation()`, `PetscSortRealWithArrayInt()`

## Level
