[Slider] Cannot set stepSize < 1.0

See original GitHub issue

Description: When I set stepSize=0.1 I get next error:

Caused by: java.lang.IllegalArgumentException: The stepSize must be 0, or a factor of the valueFrom-valueTo range
        at com.google.android.material.slider.Slider.validateStepSize(Slider.java:383)
        at com.google.android.material.slider.Slider.processAttributes(Slider.java:360)

Expected behavior: I want to set stepSize=“0.1” for range 0…1

Source code:

<com.google.android.material.slider.Slider
        android:id="@+id/sliderOpacity"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:stepSize="0.1"
        android:valueFrom="0"
        android:valueTo="1" />

Android API version: Android P, Q

Material Library version: 1.2.0-alpha01

It happens because:
} else if (stepSize > 0.0f && (valueTo - valueFrom) % stepSize != 0.0f) {
      Log.e(TAG, EXCEPTION_ILLEGAL_STEP_SIZE);
      throw new IllegalArgumentException(EXCEPTION_ILLEGAL_STEP_SIZE);
This works fine with integer values. But using float values as in your case in java it is 0.09999999 and not 0.0f.

It is annoying. Why I cant set step size I want, why that limitation?
