>Description:
The C++ standard says all functions from the standard C library from math.h should be put in namespace std by <cmath>.

asinh/acosh/atanh are in the ISO C 99 standard math.h
(at least in my draft of the std), but they are not in g++'s <cmath>.  I don't know if it's because they were not present in the previous C standard version the C++ std is based on (?).
In any case, it would be nice to have them in std:: like the others.

Compiling the following program gives :
essai_asinh.C: In function `int main()':
essai_asinh.C:6: error: `asinh' undeclared in namespace `std'
essai_asinh.C:7: error: `acosh' undeclared in namespace `std'
essai_asinh.C:8: error: `atanh' undeclared in namespace `std'
>How-To-Repeat:
#include <cmath>

int main()
{
  double d;
  std::asinh(d);
  std::acosh(d);
  std::atanh(d);
}
