Overloads

HasZeroByte(UInt64)

Checks whether the given value has any bytes that are set to 0. This method mirrors HasZeroByte(UInt32), but with UInt64 values.
HasZeroByte(UInt32)

Checks whether the given value has any bytes that are set to 0. That is, given a UInt32 value, which has a total of 4 bytes, it checks whether any of those have all the bits set to 0.

HasZeroByte(UInt64)

Checks whether the given value has any bytes that are set to 0. This method mirrors HasZeroByte(UInt32), but with UInt64 values.

public static bool HasZeroByte (ulong value);
static member HasZeroByte : uint64 -> bool
Public Shared Function HasZeroByte (value As ULong) As Boolean

Parameters

value
UInt64

The input value to check.

Returns

Boolean

Whether value has any bytes set to 0.

Applies to

HasZeroByte(UInt32)

static member HasZeroByte : uint32 -> bool
Public Shared Function HasZeroByte (value As UInteger) As Boolean

Parameters

value
UInt32

The input value to check.

Returns
