## Synopsis

PetscBool PetscEqualReal(PetscReal a, PetscReal b)
```

## Input Parameters

- ***a -*** first real number
- ***b -*** second real number





## Note
Equivalent to "a == b". Should be used to prevent compilers from
emitting floating point comparison warnings (e.g. GCC's -Wfloat-equal flag)
in PETSc header files or user code.
