Function Documentation

InternalMathARShiftU64()

UINT64 EFIAPI InternalMathARShiftU64	(	IN UINT64	Operand,
		IN UINTN	Count
	)

Shifts a 64-bit integer right between 0 and 63 bits. The high bits are filled with original integer's bit 63. The shifted value is returned.

This function shifts the 64-bit value Operand to the right by Count bits. The high Count bits are set to bit 63 of Operand. The shifted value is returned.

Parameters

Operand	The 64-bit operand to shift right.
Count	The number of bits to shift right.

Returns

Operand arithmetically shifted right by Count.
