I see that people born to parents who are both magical are pure-bloods, if either of the parental sides is muggle they are half-bloods, and if both the parents are muggles, the child is muggle-born.

But what is the blood status of the child born to a half-blood and a pure-blood? Since there are muggles in the ancestral line is he/she still a half-blood, or considering that both the parents are magical, is he/she a pure-blood?
