Number of bytes

ClearBit(Span<byte>, int)

public static void ClearBit(Span<byte> data, int index)

Parameters

data Span<byte>

index int

CountBits(ReadOnlySpan<byte>)

Counts the number of set bits in a span of bytes.

Parameters

data ReadOnlySpan<byte>

Span to count bits.

Returns

int

Count of set (one) bits.

CountBits(ReadOnlySpan<byte>, int)

Counts the number of set bits in a span of bytes starting at a specific bit index.

public static int CountBits(ReadOnlySpan<byte> data, int index)

Parameters

data ReadOnlySpan<byte>

Span to count bits.

index int

Bit index to start counting from.

Returns

int

Count of set (one) bits.

CountBits(ReadOnlySpan<byte>, int, int)

Counts the number of set bits in a span of bytes starting at a specific bit index, and limiting to a certain number of bits in the span.

public static int CountBits(ReadOnlySpan<byte> data, int index, int length)

RoundUpToMultipleOf64(long)

Rounds an integer to the nearest multiple of 64.

public static long RoundUpToMultipleOf64(long n)

Parameters

n long

Integer to round.

Returns

long

Integer rounded to the nearest multiple of 64.

RoundUpToMultipleOf8(long)

Rounds an integer to the nearest multiple of 8.
