Returns the value obtained by rotating the two's complement binary
representation of the specified int
value left by the
specified number of bits.
[Android.Runtime.Register("rotateLeft", "(II)I", "")]
public static int RotateLeft (int i, int distance);
[<Android.Runtime.Register("rotateLeft", "(II)I", "")>]
static member RotateLeft : int * int -> int
Parameters
- i
- Int32
the value whose bits are to be rotated left
- distance
- Int32
the number of bit positions to rotate left
Returns
the value obtained by rotating the two's complement binary
representation of the specified int
value left by the
specified number of bits.
- Attributes
Remarks
Returns the value obtained by rotating the two's complement binary representation of the specified int
value left by the specified number of bits. (Bits shifted out of the left hand, or high-order, side reenter on the right, or low-order.)
Note that left rotation with a negative distance is equivalent to right rotation: rotateLeft(val, -distance) == rotateRight(val, distance)
. Note also that rotation by any multiple of 32 is a no-op, so all but the last five bits of the rotation distance can be ignored, even if the distance is negative: rotateLeft(val, distance) == rotateLeft(val, distance & 0x1F)
