React Native -如何舍入动画组件的值？

import React, { useState } from 'react';
import { Animated, Button, View } from 'react-native';

const App = () => {
  const [animationValue, setAnimationValue] = useState(new Animated.Value(0));

  const startAnimation = () => {
    Animated.timing(animationValue, {
      toValue: 1.5,
      duration: 1000,
      useNativeDriver: true,
    }).start();
  };

  const roundedValue = Math.round(animationValue._value * 100) / 100;

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Animated.View
        style={{
          width: 100,
          height: 100,
          backgroundColor: 'red',
          transform: [{ scale: animationValue }],
        }}
      />
      <Button title="Start Animation" onPress={startAnimation} />
      <Text>Rounded Value: {roundedValue}</Text>
    </View>
  );
};

export default App;
