What to read about Numerical Methods and the floating number system (and especially finding the limit of machine zero in a given number system)?

Question

IT education

Good day. Recently, I started studying Numerical Methods (I took the textbook Numerical Methods by M.P. Lapchik, M.I. Ragulina, E.K. Khenner) and settled on the topic "Methods of Representing Numbers in Computers", since the topic was covered quite poorly due to the minimum number of explanations, I had a lot of questions for which the search engine gives a little different from what I wanted. Therefore, I ask you to help you with recommendations on the literature and topic I have described.

Answer 1

Need a little more specifics in your question.
Roughly speaking, all computers store numbers in the binary system, and the number of bits is limited. Hence all the difficulties when working with negative and especially fractional numbers.
