Integer與Double類型轉換

示例代碼

public class Company {
    public static void main(String[] args) {


        // 示例, 支持0.2開頭
        String currentVoltage = "20.014";

        // 轉換雙精度
        int totalFee1 = (int) (Double.parseDouble(currentVoltage));

        // 轉換單精度, 有時會使數據值變小;
        int totalFee2 = (int) (Float.parseFloat(currentVoltage));

        // 輸出 20 20
        System.out.println("totalFee1:" + totalFee1 + ",totalFee2:" + totalFee2 + ".");
        
    }
}
