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.
Computational complexity, exact linear computation, Galois-field arithmetic, Gaussian elimination, linear equations, matrix processor, p-adic arithmetic, rational arithmetic, residue arithmetic.
