Morphology

round + error

The noun 'rounding error' is directly compositional: it denotes an error caused by rounding (the process of adjusting a numeric value), so a learner who knows 'round' and 'error' can readily infer the meaning. The structure and concept are literal and common in other languages/technical contexts, making it immediately understandable to a B1 learner.

Etymology

Rounding error comes from the idea of rounding numbers to fewer decimals. The word rounding means making a number simpler and error means a small mistake, so the phrase describes the tiny mistakes that happen when we make numbers simpler by rounding.
