From Wikipedia, the free encyclopedia
Hermann Schmid is the author of the book Decimal Computation which was first published in 1974 by John Wiley & Sons (ISBN 047176180X) and reprinted in 1983 by Robert E. Krieger Publishing Company (ISBN 0898743184).
The book comprises twelve chapters describing computation in decimal:

This is probably the most complete work describing decimal calculations on computers, however later papers by other authors should be consulted also (see also the Decimal Bibliography).
