Nico <nico.schloemer at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|erf, erfc not in cmath |erf, erfc placed in global | |namespace by <cmath> | |without --std=c++11 --- Comment #1 from Nico <nico.schloemer at gmail dot com> 2012-12-14 08:26:40 UTC --- Apparently, when compiled with --std=c++11, the erf(c) functions are correctly placed in the std:: namespace. Otherwise, they're in the global namespace (this is math.h's behavior).
