_isAlmostIntmethod in theMouseWheelClassifierclass to increase the margin of error.0.01to0.01 + Number.EPSILON * 100(approximately 0.010000000000022205).Reason for Change
To account for floating-point errors in certain zoom level calculations.
Previous Behavior
deltaY = 0.996 ~ 1and_isAlmostIntcorrectly returnedtrue.deltaYof 0.9899999999999999,_isAlmostIntincorrectly returnedfalse.New Behavior
_isAlmostIntnow correctly returnstruefor zoom level 1 cases, as intended.Testing
_isAlmostIntreturnstruefordeltaYvalues very close to 1.Additional Notes
This change helps maintain consistent behavior across different zoom levels, addressing edge cases where floating-point precision was causing unexpected results.
