Another solution if the interface cant be changed is to just convert to float  as following.Since
value anyways  converted to long the conversion to float also will be fine.

{code}
  @Override
  public Resource multiplyAndNormalizeUp(Resource r, double by,
      Resource stepFactor) {
    return Resources.createResource(
        roundUp(
            (long) Math.ceil((float) (r.getMemorySize() * by)),
            stepFactor.getMemorySize()),
        roundUp(
            (int) Math.ceil((float) (r.getVirtualCores() * by)),
            stepFactor.getVirtualCores())
        );
  }
{code}
