rounding errors
Truncation's small mistakes
Rounding errors are small inaccuracies introduced when numbers are approximated to fewer decimal places than their exact values.
In computing and mathematics, these tiny discrepancies can accumulate through repeated calculations, sometimes producing noticeably wrong results: The spacecraft missed its target due to accumulated rounding errors.
The term extends to any situation where small imprecisions compound into significant problems.
