Classes
struct	external_scope
	Temporarily restores the enclosing region's caller environment for external code. Saves the current numerical state and reinstates it on return or unwind. The enclosing region must outlive this guard; both guards belong to the same thread. More...

	native_fp32_scope (native_fp32_mode mode)

	Disallows transfer of a guard whose restoration belongs to its constructing thread.

	Returns the state captured before this numerical region.

	Checks thread identity and controls; accrued exception status does not cause failure.

Detailed Description

Borrows the calling thread with RNE, masked exceptions and selected denormal controls. Saves and restores complete control/status state. The object and its nested external scopes must be destroyed on their constructing thread. It cannot be copied or moved. Construction throws on invalid/unavailable controls when exceptions are enabled; otherwise it terminates. Destruction is noexcept.
