It is a very specialized book, but easy to follow, and would interest researchers in numerical analysis as well as in computer arithmetic. The book is based on the free program coq (french for “rooster”), which is described as a proof assistant, and on an addendum package for coq called flocq that formalizes floating point operations.

Nov 7, 2008 these tools, based on the notion of 'formal proof,' have in recent years been used to provide nearly infallible proofs of many important results.
But ultimately i would say: formal proof refers to any procedure which deduces one string from a given set of strings in an accepted computer-checkable system. Note that the plurality of formal systems in the broad sense, with various strengths and weaknesses, is handled by theorems asserting the appropriate equivalence of these systems.
On the lowest abstraction level, rigorous mathematical proofs rely on formal logic. On this level, proofs can be automatically veri ed by computers. Nobody wants to write or read proofs on this level of detail. In interactive theorem proving a human guides the proof and the computer tries to ll in the details.
This book constitutes the refereed proceedings of the 13th international conference on intelligent computer mathematics, cicm 2020, held in bertinoro, italy, in july 2020*. The 15 full papers, 1 invited paper and 2 abstracts of invited papers presented were carefully reviewed and selected from a total of 35 submissions.
Because it is seldom \pure arithmetic, merelyarithmetic and something; because if they submitted to arith,we might well reject their papers! (and we probably have) necessary expertise in related areas: our community still has expertise on circuit design; we have low expertise in numerical analysis, compilation, formal proof, nite eld arithmetic.

On top of the proof assistant coq, we had implemented in previous work a toolbox for writing and checking game-based security proofs of cryptographic primitives. In this paper we describe its extension with number-theoretic capabilities so that it is now possible to write and check arithmetic-based cryptographic primitives in our toolbox.
The following proof system for integer arithmetic is based on that given in introduction to mathematical logic by elliott mendelson. T+1 (1 is not a basic symbol in this system - it could be defined as 0') first the language: constant.
From wikipedia, the free encyclopedia automated theorem proving (also known as atp or automated deduction) is a subfield of automated reasoning and mathematical logic dealing with proving mathematical theorems by computer programs. Automated reasoning over mathematical proof was a major impetus for the development of computer science.
Floating-point arithmetic is defined by the ieee-754 standard and has often been formalized. Key words: floating-point, coq, ieee-754, formal proof checking.
A renewed interest in multipoint methods has arisen in the early years of the twenty-first century due to the rapid development of digital computers, advanced computer arithmetics (multi-precision arithmetic and interval arithmetic) and symbolic computation. The mentioned improvements in hardware and software were ultimately indispensable since multipoint methods produce approximations of great accuracy and require complicated convergence analysis that is feasible only by symbolic computation.
A formal proof is a proof in which every logical inference has been checked all the way back to the fundamental axioms of mathematics. All the intermediate logical steps are supplied, without exception. No appeal is made to intuition, even if the translation from intuition to logic is routine.
Our ultimate goal is to provide guaranteed formal proofs of numerical properties with minimum human effort. As automated processes are bound to fail on degenerate cases and waste time and memory on simple ones, we have designed a set of highly customizable proof strategies.

Floating-point arithmetic is a very efficient solution to perform computations in the real field. However, it induces rounding errors making results computed in floating-point differ from what would be computed with reals.
