std::feholdexcept

Header: <cfenv>

First, saves the current floating-point environment to the object pointed to by envp (similar to std::fegetenv), then clears all floating-point status flags, and then installs the non-stop mode: future floating-point exceptions will not interrupt execution (will not trap), until the floating-point environment is restored by std::feupdateenv or std::fesetenv.
