Simplified method for recognizing zero in constants

"This volume contains the text of the forty research papers presented at the 1995 International Symposium on Symbolic and Algebraic Computation. ISSAC'95 is the most recent meeting in a well established series bringing together workers in all areas of symbolic mathematical computation. This year the meeting was held July 10-12 at Concordia University in Montreal, Canada, under the sponsorship of ACM SIGSAM and SIGNUM." "The papers presented here cover both the mathematical and the software aspects of symbolic computation: Groups, Linear Algebra, Algebraic Numbers, Algebraic Geometry, Polynomial and Differential Algebra, Differential and Difference Equations, Seminumerical Methods, Software Systems and Visualization."--BOOK JACKET.
