| int fegetenv( fenv_t* envp ); |
(1) | (since C99) |
| int fesetenv( const fenv_t* envp ); |
(2) | (since C99) |
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 feholdexcept or 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 fetestexcept), but the corresponding floating-point exceptions are not raised (execution continues uninterrupted)
