Int16AlgorithmsExtensions.RotateRight(this short, int) Method

Performs a bitwise right rotation on a number.

public static short RotateRight(this short number, int count);

Parameters

number System.Int16

The number to rotate

count System.Int32

the number of bits to rotate

Returns

System.Int16 The rotated value.

Example

var rotationBase = sizeof(short)-5;

ushort ub = 0b11110000_00000000;

short b = (short)ub;

var b2 = b.RotateRight(rotationBase+0); // b2 = 0b00000000_00011110
var b3 = b.RotateRight(rotationBase+1); // b3 = 0b00000000_00001111
var b4 = b.RotateRight(rotationBase+2); // b4 = 0b10000000_00000111
var b5 = b.RotateRight(rotationBase+3); // b5 = 0b11000000_00000011
var b6 = b.RotateRight(rotationBase+4); // b6 = 0b11100000_00000001
var b7 = b.RotateRight(rotationBase+5); // b7 = 0b11110000_00000000
