# PetscOptionsRealArray
Gets an array of double values for a particular option in the database. The values must be separated with commas with no intervening spaces.
## Synopsis
```
#include "petscsys.h"
PetscErrorCode PetscOptionsRealArray(const char opt[],const char text[],const char man[],PetscReal value[],PetscInt *n,PetscBool *set)
```
Logically Collective on the communicator passed in `PetscOptionsBegin()`
## Input Parameters
- ***opt -*** the option one is seeking
- ***text -*** short string describing option
- ***man -*** manual page for option
- ***n -*** maximum number of values that value has room for
## Output Parameters
- ***value -*** location to copy values
- ***n -*** actual number of values found
- ***set -*** `PETSC_TRUE` if found, else `PETSC_FALSE`
## Note
Must be between a `PetscOptionsBegin()` and a `PetscOptionsEnd()`
