| ScopedFpeState () | |
| Start a scope that will be restored, without changing the current state. | |
| ScopedFpeState (bool exceptions_enabled) | |
Start a scope with the specified exception state. This is equivalent to calling the default constructor followed by set_exceptions. | |
| ScopedFpeState (DoNotSave) | |
Start a scope without saving the current state. The only valid method call from this state is save_exceptions. | |
| void | set_exceptions (bool exceptions_enabled) const |
| Enable or disable floating point exceptions. It is an error if the exception state is not currently saved. | |
| void | save_exceptions () |
Save the current exception handling state after it has been cleared by restore_exceptions. It will be restored by a later call to restore_exceptions. It is an error to call this if a state is already saved. | |
| void | restore_exceptions () |
| Restore the FPE handling to the internally saved state if present and clear that state. This is called automatically by the destructor if it is not called manually. | |
