How does Compositor Animation make every change to an integer?

[sudongg]

I try to use composer animation for offset animation

      var func = Compositor.CreateLinearEasingFunction(); ;
            var offsetXAnimation = Compositor.CreateScalarKeyFrameAnimation();
            offsetXAnimation.Duration = TimeSpan.FromSeconds(5);
            CompositionVisual.StartAnimation("Offset.X", offsetXAnimation);

When the Visual is a shape, the animation is smooth, but when the Visual is a text, the animation becomes jittery, I want to convert the value of each change to an integer, this should reduce the jitter, please tell me how to do it .
