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); } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
