: Instead in these cases (check other examples) ε/eps/epsilon is just the value we shift a point in order to '''simplistically''' cope with a specific problem. Not the best we can do, and it has "side effects": already considered in the text, thus no surprise (except for you, it seems).
: If we need to be pedantic and focus on all the details for a production ready implementation (which isn't the main aim of this wiki, as far as I understand it), floating point should be treated carefully in every comparisons, but many did the naive approach — I think because it isn't the point of the task (or maybe because we hope the target CPU has an instruction like FCMPE in MMIX — just joking). --- [[User:ShinTakezou|ShinTakezou]] ([[User talk:ShinTakezou|talk]]) 18:59, 23 February 2018 (UTC)
