Kent-san, Thank you. Tests with events worked fine.


I found another issue to be discussed.

1. <input type="number" min="0" value="0" step="0.003921568627450980" max="1" />
2. stepUp() for 255 times.
3. stepDown() for 255 times. => 3.838e-15 (0 is expected.)

My patch removes numeric errors with "decimal places" as the bug 48308 does. (The maximum decimal places of step and the current value, not base.)

This error removing does not work for the case above. The decimal places of step are large. We could remove this rounding error with stepwise adjustment at stepUp()/stepDown().

This example is shown at HTML5 - 4.10.7.2.11 The step attribute.


I've added Gavin
