Int64AlgorithmsExtensions.RoundUpToPowerOfTwo(this long) Method

For any given number return the number if it’s a power of two, or return the next higher power of two capable of fitting in the data type. For negative values or values that would result in a negative next higher power of two, zero is returned. (e.g. number > 2^(k-2) where k is the bit size.)

public static long RoundUpToPowerOfTwo(this long number);

Parameters

number System.Int64

The number to evaluate.

Returns

System.Int64

Example

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

v = 3;
Console.WriteLine($"{v.RoundUpToPowerOfTwo()}"); // outputs: 4
