Chrome uses the "nearest" strategy that JS's Math.round() uses. "nearest" is also the default rounding for the round() CSS function Here is a reduced test case showing the differences: https://codepen.io/propjockey/pen/vYvMbaX/253c4756c72e962cb10b0c19b396ea37?editors=1100 Thank you! // Jane 1985108 1 ntim 2023-10-14 08:00:46 -0700 I switched to using a towards positive infinity rounding strategy in bug 260777. Can you please re-test in STP? *** This bug has been marked as a duplicate of bug 260777 ***
