Summary
Unpacks a set of bits into an array of booleans.
Pascal
procedure BitsToBooleans(const Bits: Byte; var B: TBooleanArray; AllBits: Boolean = False); overload;
procedure BitsToBooleans(const Bits: Word; var B: TBooleanArray; AllBits: Boolean = False); overload;
procedure BitsToBooleans(const Bits: Integer; var B: TBooleanArray; AllBits: Boolean = False); overload;
procedure BitsToBooleans(const Bits: Int64; var B: TBooleanArray; AllBits: Boolean = False); overload;
Parameters
| Parameters | Description |
| const Bits: Byte | The set of bits to unpack to an array of Booleans. |
| var B: TBooleanArray | Array which receives the bits in Bits unpacked as Booleans. |
| AllBits: Boolean = False | If set to True the number of elements in the resulting array equals the number of bits in the Bits parameter (ie 8 for Byte, 16 for Word, etc). If False the number of elements in the resulting array equals the position of the highest set bit. |
Description
BitsToBooleans unpacks a set of bits into an array of Booleans. Each set bit in the Bits parameter results in a True valued Boolean while each cleared bit results in a False valued boolean. The resulting array has one element for each bit in the Bits parameter where bit 0 corresponds to B[0], bit 1 to B[1] etc. See also BooleansToBits for the inverse operation. If the AllBits parameter is True, the number of elements in the resulting array is the same as the number of bits in the Bits parameter, if set to False (the default) the resulting array has only as many elements as is required to hold the highest set bit position. For example, if Bits equals 2 than the highest set bit is bit 1 and the resulting array has only two elements: [True, False].
