[Jie Fu]

> Hi all,
> 
> `GraphKit::dprecision_rounding` and `GraphKit::dstore_rounding` are duplicate.
> It would be better to remove one of them.
> 
> The patch removes `GraphKit::dstore_rounding` and replaces all the usages with `GraphKit::dprecision_rounding`.
> 
> Thanks.
> Best regards,
> Jie
