Any non elastic/linear easing's do not work

Any of the easing functions do not work.
```
<AnimatedNumber value={20} easing={'easeInQuart'} formatValue={(value) => {
    console.log(value)
    return value;
}}/>
```

Received value on `formatValue` is "0", during the animation it is "NaN" and at the complete it is "20".
