equals
Rounded, orientation-sensitive identity: equal when every component matches at the SCALE quantum.
+e423 ≠ −e423 — the negated line cuts the same point set with the opposite orientation and compares unequal; compare canonical on both sides for unoriented equivalence. At-infinity magnitudes compare as data. Identity is exact-class: a subclass instance and a plain Line never compare equal.
Return
true iff other shares this object's exact class and its three components all match after rounding.
Parameters
other
The object to compare against.
