rounding error
Truncation's tiny discrepancy
A rounding error is the small discrepancy that results when a number is rounded to fewer decimal places than its exact value: The total was off by a few cents due to rounding error.
In computing and finance, rounding errors can accumulate across many calculations.
Figuratively, something dismissed as a rounding error is too small to matter: Their market share is a rounding error compared to the industry leaders.
