Microprocessors such as the Intel 8008, the direct predecessor of the 8080 and the 8086, used in early personal computers, could also perform a small number of operations on four bits, such as the DAA ( Decimal Add Adjust ) instruction, and the auxiliary carry ( AC / NA ) flag, which were used to implement decimal arithmetic routines.

He also greatly disliked the Dewey Decimal system.

The failure of the system to catch on in North America was partly because of its internal deficiencies but also because the Dewey Decimal and Library of Congress systems were already well established.

Decimal notation often refers to a base-10 positional notation such as the Hindu-Arabic numeral system ; however, it can also be used more generally to refer to non-positional systems such as Roman or Chinese numerals which are also based on powers of ten.

Most classification systems like the Dewey Decimal Classification ( DDC ) and Library of Congress classification also add a cutter number to each work which adds a code for the author of the work.
