Abstract

In the paper the peculiarities of using multi-bit arithmetic in mathematical modeling are investigated. An experimental study of means of improving the accuracy of computer results of solving poorly ill-conditioned systems of linear algebraic equations using the GMP library is described to improve the accuracy of calculations.
