abs vs flabs

["Allan Stokes" <allan@xxxxxxxxx>]

Yes, Jim's comment is correct.  This is a case where C++ takes advantage of
operator overloading to define abs() separately for each of int, long,
float, double, and long double.  In C++ fabs and labs are unnecessary flesh.

Stroustrup says <cmath> and <math.h> are supposed to include

  double abs(double);

Is that not true.
