BitUtil.LongFromByteArray Method

Interprets a byte array as MSB first (leftmost bit) and allows extraction, of a long (64 bit) value by byte offset, bit offset and number of bits COUNTING BITS FROM LSB to MSB i.e. right to left.

numberOfBits: Type: int
The number of bits that need to be extracted from the byte array.

Return Value

Type: long

Returns a 64-bit long value.
