Restore the floating-point environment and raise any previously raised exceptions
#include <fenv.h> int feupdateenv( const fenv_t *envp );
The feupdateenv() function restores the floating-point environment the object that envp points to, and then raises any previously raised exceptions that were saved.
You can use this function to end the nonstop mode that was earlier installed by feholdexcept().
