Matrix Processors Using p-adic Arithmetic for Exact Linear Computations
July 1977 (vol. 26 no. 7)
pp. 633-639
E.V. Krishnamurthy, Department of Applied Mathematics, Indian Institute of Science
A unique code (called Hensel's code) is derived for a rational number by truncating its infinite p-adic expansion. The four basic arithmetic algorithms for these codes are described and their application to rational matrix computations is demonstrated by solving a system of linear equations exactly, using the Gaussian elimination procedure.
