Rect and RectF in Android SDK

Question

What is the difference between Rect and RectF in the Android SDK?

Answer 1

Rect is final, RectF can be extended

Answer 2

Using Rect you define its edges using integers and using RectF they are defined as floats.

Looking at them more carefully I have spotted a few differences actually. I will only list what one implementation has more compared to the other one.

Rect

• equals(Object obj) (for some reason it has its own implementation of equals)
• exactCenterX()
• exactCenterY()
• flattenToString()
• toShortString()
• unflattenFromString(String str)

RectF

• round(Rect dst)
• roundOut(Rect dst)
• set(Rect src)

So apparently there are some differences.
