Defined in header
<cfenv>
int fegetenv( std::fenv_t * envp )
(1)
(since C++11)
int fesetenv( const std::fenv_t * envp );
(2)
(since C++11)
Manages the status of the floating-point environment.
1) Attempts to store the status of the floating-point environment in the object pointed to by
envp.2) 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)[edit] Parameters
envp
-
pointer to the object of type std::fenv_t which holds the status of the floating-point environment
[edit] Return value
0 on success, non-zero otherwise.
