When reporting numbers, it is suggested not to use three digits after the decimal point to avoid confusion with the thousands separator.
In software development, it is recommended to use libraries to handle numeric input and output according to local conventions to prevent errors.
An incident in 2006 during a course on Bayesian clinical trial design in Bordeaux highlighted the issue of decimal separator differences between the US and France causing software problems.
The solution in the mentioned incident was for attendees to set their operating system locale to the US to overcome the issue of conflicting decimal notation formats.
