A floating-point is a way of representing and performing arithmetic operations on real numbers in computing. It's a numerical data type that allows you to handle values with fractional parts and a wide range of magnitudes. The term "floating-point" refers to the fact that the decimal point ...
In this work, we analyse and discuss the impact of floating point precision reduction (single and mixed with respect to double) on real CFD applications using OpenFOAM. In particular, we consider two important aspects such as the convergence and accuracy of computed solutions, the computational pe...

PURPOSE:To execute an arithmetic without generating overflow or underflow by constituting a computing element which can execute the four rules of arithmetic by means of dealing with a floating point data system defined by the means of a specified expression. CONSTITUTION:The computing element which ...
The Accuracy Of Floating Point Summation The usual recursive summation technique is just one of several ways of computing the sum of n floating point numbers. Five summation methods and their vari... Higham,J Nicholas - 《Siam Journal on Scientific Computing》 被引量: 354发表: 1993年 A ...
Abstract Most mathematical formulae are defined in terms of operations on real numbers, but computers can only operate on numeric values with finite precision and range. Using floating-point values as real numbers does not clearly identify the precision with which each value must be represented. To...
floating-point英英释义 Floating point In computing, floating point describes a method of representing an approximation of a real number in a way that can support a wide range of values. The numbers are, in general, represented approximately to a fixed number of significant digits (the mantissa...
Computation with real numbers is not very practical because it involves limits and infinities. Instead, MATLAB®and most other technical computing environments use floating-point arithmetic, which involves a finite set of numbers with finite precision. This leads to phenomena like roundoff error, ...
For example, when a floating-point number is in error by n ulps, that means that the number of contaminated digits is log n. If the relative error in a computation is n, then (3) contaminated digits log n.Guard Digits One method of computing the difference between two floating-point ...
A Generic Library of Floating-Point Numbers and its Application to Exact Computing In this paper we present a general library to reason about floating-point numbers within the Coq system. Most of the results of the library are proved for an arbitrary floating-point format and an arbitrary base...
