Is C really used for new scientific and engineering applications these days? I had thought that the main non-Fortran languages for those domains were now C++ (with a negative growth rate) and Python (with a definitely positive growth rate).
Also, if these routines are part of the required math library for C, can’t Fortran programmers just call them directly using bind(c) interfaces? !6.9 already has 199 subclauses. It seems that adding yet more intrinsics should have a fairly high use case threshold for justification.
Cheers,
