[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

the value obtained by rotating the two's complement binary representation of the specified int value left by the specified number of bits.

Attributes

RegisterAttribute

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).
