### 295. Is abs defined in <cmath>?

Discussion:

Table 80 lists the contents of the <cmath> header. It does not list `abs()`. However, 26.5, paragraph 6, which lists added signatures present in <cmath>, does say that several overloads of `abs()` should be defined in <cmath>.

Proposed resolution:

Add `abs` to Table 80. Also, remove the parenthetical list of functions "(abs(), div(), rand(), srand())" from 28.6 [numarray], paragraph 1.

[Copenhagen: Modified proposed resolution so that it also gets rid of that vestigial list of functions in paragraph 1.]

Rationale:

All this DR does is fix a typo; it's uncontroversial. A separate question is whether we're doing the right thing in putting some overloads in <cmath> that we aren't also putting in <cstdlib>. That's issue 323.
