can someone guide me how to decode the toAddress and quantity of an ERC20 Token. I am able to get toAddress but amount I am receiving is without decimal input.

Below is the decode method I am using. :

public void decodeInput(String data) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
    String inputData = data;
    String method = inputData.substring(0,10);
    log.info("Method >>>>>> " +method);
    String to = inputData.substring(10,74);
    String value = inputData.substring(74);
    Method refMethod = TypeDecoder.class.getDeclaredMethod("decode",String.class,int.class,Class.class);
    refMethod.setAccessible(true);
    Address address = (Address)refMethod.invoke(null,to,0,Address.class);
    log.info("Address>>>>>> " +address.toString());
    Uint256 amount = (Uint256) refMethod.invoke(null,value,0,Uint256.class);
    log.info("amount >>>>>> " +amount);
}

There's no decimal in solidity: you've to divide the returned number with the number of decimal of your token

Did that. but it rounds up completely. Let's say amount is 100.50 I get data from logs as 100500000. So dividing it by 1000000 should give me 100.50. But it returns only 100. I have tried different rounding method as well.
