MouseWheel event - precise or not?

Hi, I have a question about mouse wheel event
In browser, I have the following property

Which tells me if a wheel event “precise” or not.
So that my code looks like:
double k = e.getDeltaMode() == 1 ? 40 : 1;
double deltaX = e.getDeltaX() * k;

On windows wheel events are rare ( and the deltaMode equals to 1), on mac they are very frequent and precise (and deltaMode == 0).

On windows I get SDL wheel event with +1 or -1. I do not have implementation for mac yet, it is coming.
But it seems that SDL does not have such property for wheel event and on mac I will probably see many frequent events.

Isn’t it the case ?
