A quantitative probabilistic investigation into the accumulation of rounding errors in numerical ODE solution. [PDF]

open access: yes, 2009
We examine numerical rounding errors of some deterministic solvers for systems of ordinary differential equations (ODEs) from a probabilistic viewpoint. We show that the accumulation of rounding errors results in a solution which is inherently random and

Lossless audio coding using the IntMDCT and rounding error shaping

open access: yes, 2022
S.2201-2211In this paper, lossless audio coding using the integer modified discrete cosine transform (IntMDCT) is discussed. The IntMDCT is constructed as an integer approximation of the MDCT using the lifting scheme and is reversible. The rounding error

Goldilocks Rounding: Achieving Balance Between Accuracy and Parsimony in the Reporting of Relative Effect Estimates

open access: yesCancer Informatics, 2021
Researchers often report a measure to several decimal places more than what is sensible or realistic. Rounding involves replacing a number with a value of lesser accuracy while minimizing the practical loss of validity.

Discretization vs. rounding error in Euler's method [PDF]

open access: yes, 2011
The article of record as published may be located at http://dx.doi.org/10.4169/college.math.j.42.5.399Euler’s method for solving initial value problems is a good vehicle for observing the relationship between discretization error and rounding error in ...

Probabilistic Rounding Error Analysis of Householder QR Factorization [PDF]

open access: yes, 2022
When an $m\times n$ matrix is premultiplied by a product of $n$ Householder matrices the worst-case normwise rounding error bound is proportional to $mnu$, where $u$ is the unit roundoff.

Computing a correct and tight rounding error bound using rounding-to-nearest [PDF]

open access: yes, 2016
International audienceWhen a floating-point computation is done, it is most of the time incorrect. The rounding error can be bounded by folklore formulas, such as ε|x| or ε| o (x)|.

Divisions and Square Roots with Tight Error Analysis from Newton–Raphson Iteration in Secure Fixed-Point Arithmetic

open access: yesCryptography, 2023
In this paper, we present new variants of Newton–Raphson-based protocols for the secure computation of the reciprocal and the (reciprocal) square root.

ROUNDING ERRORS AND THEIR EFFECTS

open access: yesFar East Journal of Mathematical Education, 2021
The motivation to write this paper is the fact that students often blindly trust the results of a computation with the computer and rarely question the results. The general opinion is that the computer is perfect and errors only come into the game because of human errors such as faulty programs or incorrect operation.
