std::feholdexcept
Min standard notice:
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.
# Declarations
int feholdexcept( std::fenv_t* envp )
(since C++11)
# Parameters
envp: pointer to the object of type std::fenv_t where the floating-point environment will be stored
# Return value
0 on success, non-zero otherwise.
