This article provides an analytical review of approaches to solving the forward analysis problem. This task belongs to one of the main functional tasks of computer-measuring systems and complexes.

An adequate and most favorable method for solving the problem, based on prefractal arithmetic, has been selected. This approach alone makes it possible to solve this problem in real time and provides the functionality of systems and complexes of this class.

The software package was tested. It is shown that the use of this method fully ensures the solution of the forward analysis problem, leading simultaneously to an improvement in the performance characteristics of systems.

A discussion was held on the development of solutions to forward analysis problems.

The program and its fragments can be used to conduct computational experiments to conduct research on the subtle properties of computational algorithms used in engineering and scientific calculations

Keywords: normalized number, floating-point number, overflow, rounding error, Ulp, underflow, algorithm, relations, lexicographic order, and Boolean order, forward analysis.
