UInt32AlgorithmsExtensions.GetHighestBitSet(this uint) Method

Calculate the index of the highest bit that’s been set.

public static int GetHighestBitSet(this uint number);

Parameters

number System.UInt32

The number to evaluate.

Returns

System.Int32 The index of the highest bit that’s been set; or -1 if none were set.

Example

uint v = 1;
Console.WriteLine($"{v.GetHighestBitSet()}"); // outputs: 0

v = 2;
Console.WriteLine($"{v.GetHighestBitSet()}"); // outputs: 1

v = 3;
Console.WriteLine($"{v.GetHighestBitSet()}"); // outputs: 1

v = 4;
Console.WriteLine($"{v.GetHighestBitSet()}"); // outputs: 2
