Computing a correct and tight rounding error bound using rounding-to-nearest [PDF]
, 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)|.

ROUNDING ERRORS AND THEIR EFFECTS
Far 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.

Arpra: An Arbitrary Precision Range Analysis Library
Frontiers in Neuroinformatics, 2021 Motivated by the challenge of investigating the reproducibility of spiking neural network simulations, we have developed the Arpra library: an open source C library for arbitrary precision range analysis based on the mixed Interval Arithmetic (IA)/Affine

Modeling Round-Off Errors in Hydrodynamic Simulations [PDF]
, 2022 The growth of the computing capacities makes it possible to obtain more and more precise simulation results. These results are often calculated in binary64 with the idea that round-off errors are not significant. However, exascale is pushing back the known limits and the problems of accumulating round-off errors could come back and require increasing ...

Journal of Advances in Modeling Earth Systems, 2020 The need for high‐precision calculations with 64‐bit or 32‐bit floating‐point arithmetic for weather and climate models is questioned. Lower‐precision numbers can accelerate simulations and are increasingly supported by modern computing hardware.

Stochastic Rounding and its Probabilistic Backward Error Analysis [PDF]
, 2020 Stochastic rounding rounds a real number to the next larger or smaller floating-point number with probabilities $1$ minus the relative distances to those numbers.

Reducing error in anticoagulant dosing via multidisciplinary team rounding at point of care
Clinics and Practice, 2017 The incorporation of a clinical pharmacist in daily rounding can help identify and correct errors related to anticoagulation dosing. Inappropriate anticoagulant dosing increases the risk of developing significant bleeding diathesis.

Evaluation of lossless and lossy algorithms for the compression of scientific datasets in netCDF-4 or HDF5 files [PDF]
Geoscientific Model Development, 2019 The increasing volume of scientific datasets requires the use of compression to reduce data storage and transmission costs, especially for the oceanographic or meteorological datasets generated by Earth observation mission ground segments. These data are

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
