Attempts to establish the floating-point environment from the object pointed to by
envp. The value of that object must be previously obtained by a call to std::feholdexcept or std::fegetenv or be a floating-point macro constant. If any of the floating-point status flags are set in envp, they become set in the environment (and are then testable with std::fetestexcept), but the corresponding floating-point exceptions are not raised (execution continues uninterrupted)The text has been machine-translated via Google Translate.
