Morphology

roundness = round (semi-transparent) = round + ness

Formed from 'round' + '-ness', but the meaning is an abstract/metaphorical extension to numbers (approximation), which may not be fully predictable to all learners.

Etymology

Roundness in numbers comes from the same round as the verb 'to round' a number, which means to make it 'whole' or 'neat'. So this roundness means a number is simple or approximate rather than exact.
