I chose to add them there, since other resources (such as cppreference) seem to think that C++11 should be the standard these functions were introduced, and I don't know of any reason to do otherwise. Tested on x86_64-linux. -- 8< -- This patch adds the -f and -l variants of the C89 functions to under namespace std (so std::sqrtf, std::fabsl, etc.) for C++11 and up. libstdc++-v3/ChangeLog: PR libstdc++/79700 * include/c_global/cmath (acosf, acosl, asinf, asinl, atanf, atanl, atan2f, atan2l, ceilf, ceill, cosf, cosl, coshf, coshl, expf, expl, fabsf, fabsl, floorf, floorl, fmodf, fmodl, frexpf, frexpl, ldexpf, ldexpl, logf, logl, log10f, log10l, modff, modfl, powf, powl, sinf, sinl, sinhf, sinhl, sqrtf, sqrtl, tanf, tanl, tanhf, tanhl): Add aliases in namespace std. * testsuite/26_numerics/headers/cmath/functions_std_c++17.cc: Add checks for existence of above names.
