## Description
When using the `SfRating` control to display a star rating value set to half-precision, the Android version of the control frequently displays values incorrectly.
**Key Files:**
- [StarRatingBugPage.xaml](StarRatingBug/StarRatingBugPage.xaml): The UI for this app. Here we are data-binding an integer value of 0-10 to the star rating control, dividing it by 2 using a value converter and then using the `SfRating` control to display that value at `Half` precision (EG: 0, 0.5, 1, 1.5 etc through to 5).
**Sample Xaml:**
```
<?xml version="1.0" encoding="utf-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

xmlns:sf="clr-namespace:Syncfusion.SfRating.XForms;assembly=Syncfusion.SfRating.XForms"

<StackLayout Padding="0,20,0,0">

<sf:SfRatingSettings RatedFill="#F6FF00"

</sf:SfRating.RatingSettings>
</sf:SfRating>
<Button HorizontalOptions="Center"
Text="Tap for random int value from 0 to 10"

<Label Text="{Binding Value, Converter={StaticResource valueToMessageConverter}, Mode=OneWay}"/>
</StackLayout>
</ContentPage>
```
## Steps To Reproduce
1. Clone the following repository: https://github.com/matthewrdev/syncfusion-star-rating-bug
2. Open StarRatingBug.sln in Xamarin Studio for Mac.
3. Build the project.
4. **IMPORTANT: Run project on an ANDROID emulator/device**
5. Repeatedly tap the button titled `TAP FOR RANDOM INT VALUE FROM 0 TO 10`.
6. Observe that the text saying the expected rating and the star rating are matching.
7. Eventually, the star rating control will display a value half a value out or sync.
## Expected Result
The star rating control correctly displays decimal values at half-precision.
## Actual Result
The star rating control frequently displays an incorrect half-precision value.
