The article presents the results of studying the topological properties of sets of standardized floating-point data FBA std IEEE-754 using the author's research complex. A formal description of the main elements of the structure of the complex and methods of its application is given. The distinctive features of the complex are revealed in the part of the study of FPF. The results of the study of the basic float - FNS format are presented.The commonality of the interface solutions of the complex provides the possibility of its application in mathematical modeling systems and numerical experiments, including using within the framework of standard packages.
