leastsignificantfirst
Leastsignificantfirst, or least significant first (LSF), is a convention for ordering the components of a numeric value or data sequence such that the least significant unit is placed at the beginning. In this order, the significance increases as you move later in the sequence.
In applications to numbers, sequences of digits or limbs are often stored or processed with the least
Endianness in computer memory is a related concept: little-endian systems store the least significant byte first,
LSF is also encountered in data encoding and serial communication where individual bits or bytes are transmitted
In software libraries for big integers and cryptography, internal representations are often little-endian, facilitating arithmetic operations
