	y specifies the number of bits in x that the function rotates. If y is greater than 0, the function shifts the first y bits at the left end of x to the right end. If y is less than 0, the function shifts the first y bits at the right end of x to the left end.
	If x is an 8-, 16-, 32-, or 64-bit integer, then for any value of y, y ± 8, y ± 16, y ± 32, or y ± 64 yields the same output value, respectively, as y. For example, if x is an 8-bit integer, y = 1 and y = 9 yield the same result.
	x rotated left by y is the result of the rotation. The data type of x rotated left by y is determined by the data type of the x input.

The following table illustrates how x and y affect x rotated left by y:

y	x	x rotated left by y	Comments
1	3 (00000011)	6 (00000110)	This function shifts the first one bit on the left, 0, to the right end.
2	3 (00000011)	12 (00001100)	This function shifts the first two bits on the left, 00, to the right end.
–3	3 (00000011)	96 (01100000)	This function shifts the first three bits on the right, 011, to the left end.
