  PlanetMath: least significant digit
In the case of a transcendental number, there is no actual least significant digit, but for computational purposes the rational approximation would have a least significant digit.
In binary, the least significant digit is often called the least significant bit.
This is version 2 of least significant digit, born on 2006-10-27, modified 2006-10-31.

 LSB - Least Significant Bit (or Byte)
For "Least Significant Byte." The LSB value is the second half of a full MIDI Bank Select message (the first half is the MSB value).
The rightmost bit in a byte or the rightmost byte in a big-endian word, that is, the bit or byte with the minimum value.
The bit in a binary value that carries the least weight, this is bit 0, weight 1.

 Xiao Steganography
The high-order or most significant bit is the one with the highest arithmetic value (i.e., 27=128), whereas the low-order or least significant bit is the one with the lowest arithmetic value (i.e., 20=1).
Least significant bit substitution can be used to overwrite legitimate RGB color encodings or palette pointers in GIF and BMP files, coefficients in JPEG files, and pulse code modulation levels in audio files.
By overwriting the least significant bit, the numeric value of the byte changes very little and is least likely to be detected by the human eye or ear.

 Bit Functions
Bit positions in the binary representation are numbered from right (least significant bit) to left (most significant bit); the rightmost bit position is numbered 0.
Bit 1 of the result comes from applying the specified logical operation to bit 1 of the argument, and so on for all of the bits of the result.
All the high-order bits in the pattern from the last significant bit of the value up to bit n are the same as bit n.

 ANSI C and C++ Bit Manipulation Libraries
Every bit file is referenced by a structure which includes a FILE pointer, a character to buffer bits, and count of the number of bits in the character buffer.
Set the least significant bit (lsb) of the character buffer to the bit being written.
Once 8 bits have been written to the character buffer, the buffer is written to the underlying file and the bit count is set to 0.

 Bit::Vector - phpMan   (Site not responding. Last check: 2007-10-11)
In method ""Multiply()"", all three bit vector arguments must in principle obey the rule of matching sizes, but the bit vector in which the result of the multiplication is to be stored may be larger than the two bit vector arguments containing the factors for the multiplication.
I.e., the least significant bit of "$vec1" becomes the most significant bit of "$vec2", whereas the most significant bit of "$vec1" becomes the least significant bit of "$vec2", and so forth for all bits in between.
The given bit vector is thereby filled in ascending order: The first chunk from the list (i.e., "$chunks[0]") fills the "$chunksize" least significant bits, the next chunk from the list ("$chunks[1]") fills the bits number "$chunksize" to number ""2*$chunksize-1"", the third chunk ("$chunks[2]") fills the bits number ""2*$chunksize"", to number ""3*$chunksize-1"", and so on.

 Fast binary coded decimal incrementing circuit - Patent 4256954
The sampling circuit samples the most significant bit of a BCD digit when the least significant bit of the same digit is being outputted from the memory.
The adder circuit adds one to the least significant bit in response to a control signal or one to the other bits in response to a carry condition in the adder and to a decimal carry signal.
Sampling means are coupled to the shift register at a point whereby the most significant bit of a binary coded decimal digit is outputted therefrom when the least significant bit of the same binary coded decimal digit is being outputted from the output of the memory.

 bit order   (Site not responding. Last check: 2007-10-11)
Ever since the start of asynchronous communications, the bits have been sent down the wire with the least significant data bit first and the most significant bit last.
For an asynchronous transmission, this means that the line usually is at the low voltage (OV or -12V) and that a logic 0 is sent as a high voltage (+5V or +12V).
The least significant bit of the character follows the start bit (rather than the most significant as one may have expected), followed by the rest of the bits in the byte, the parity bit (if present) and the stop bit.

 When Features Collide
When the bit is zero, the most significant bit of a byte is considered to be bit 0, and the least significant bit is bit 7.
When the bit is one, the most significant bit of a byte is considered to be bit 7, and the least significant bit is bit 0.
When this bit is set to 1, it is presumed that numbers, when in printed format, appear with their least significant digit in the first position as well, as is the case in documents printed in languages with a right-to-left direction of reading.

 QccBitBufferGetChar.3
When one writes a stream of bits to a file, it is necessary for the bits to be "packed" into byte-sized characters, as the byte is the smallest input/output unit supported by the operating system.
For reading, bits are unpacked from the current character; when no more bits remain to be read from the character, the next character from the file is read automatically.
The bit is returned in bit_value; a 0 is returned for a 0 bit, a 1 is returned for a 1 bit.

 Byte and Bit Order Dissection | Linux Journal
This means the most significant byte of an integer field is placed at a lower wire byte address and transmitted/received in front of the least significant byte.
The bit transmission/reception order generally is invisible to the CPU and software, but is important to hardware considerations such as the serdes (serializer/deserializer) of PHY and the wiring of NIC device data lines to the bus.
What is meant is that in big-endian, bit 0 is the most significant bit and in little-endian, bit 7 is the most significant bit (for a single byte).

 Bit Counting and Similar Instructions
My experience is that I want the most significant bit 10 times for every time I want one of the others, but I suspect that is because of the sort of algorithms I look at rather than any inherent importance of the operation.
What is wanted is to read a bit stream from a position given by a bit pointer, find the distance to the next 1 in the stream, and update the pointer, with appropriate interrupts if the stream becomes exhausted or there are no 1's remaining bits in the stream.
The use I envision for this is to generate non-uniform random variables, by using small numbers of bits and exact computation to obtain some of the bits of the output random variable, the rest to be filled in by random bits.
