类 NumberBaseOpt

java.lang.Object

com.centit.support.algorithm.NumberBaseOpt

public abstract class NumberBaseOpt
extends Object

1. capitalization 将数据转换为大写，用户发票中的大写输出。 2. uppercaseCN 将数据转换为中文，比如 2017 - 二〇一七。 3. getNumByte 获取数据字符串中某一位上的数值，比如获取十位上的数据参数就传入 2 4. castObjectTo* 一组类型转换算法 5. compareTwo* 数据之间比较，主要是为了避免 NullPointerException。 6. parse* 转换字符串为数值类型， 主要是为了避免 NullPointerException。
