A graph that checks "time - late == 6" after On timer (#224) failed, because the difference comes out as 5.999999999999972. Both values are sums of measured frame times, and they round along different paths. The only workaround was a Round node in front of every comparison. - New helper nearlyEqual in values.ts. Two numbers count as equal when |a - b| <= 1e-9 * max(1, |a|, |b|). The tolerance grows with the size of the values, so it holds for hours of summed dt. - Compare uses the rule for all six operators. "<" and ">" only hold when the values are not nearly equal, "<=" and ">=" also hold when they are. So "==" and ">" are never true at the same time. - Equals uses the same rule when both inputs are real numbers. Objects still compare by identity, everything else as text. The node description says so. - The tolerance is fixed, there is no parameter on the node. Physics values come from float32 in Rapier and are not covered on purpose. - The log display is unchanged and still prints the raw number. Tests: - ./check.sh: 156 files, 2311 tests, CHECK EXIT 0 (before 2300). - 11 new cases in node-catalog.test.ts, including the value from the log against 6, growth with magnitude, 6.001 != 6 and 1e-6 > 0. - Counter-check exact compare: exactly the 8 noise cases fail. - Counter-check "<"/">" without the exclusion: exactly 2 cases fail. - No e2e change, the check sum stays at 1374.
