Java Floating Point-to-RMB reading method and java reading Method

Conversion of Java floating point to RMB reading

 

• The number of the [integer part] starts from a single digit. The four digits are divided into one group. If the highest digit does not have a number, 0 is added, and the total number of arrays is recorded. There are three groups in total, it is also a 3*4 two-dimensional array;
• For unified processing of each array, the "zero" at the beginning will be removed, and the "zero" before the words "million" and "Ten Thousand" and "RMB" will be removed;
• When 0 is read, check whether the previous digit is 0. If the previous digit is 0, no processing is performed. If the previous digit is not 0 or the previous digit does not exist, write down "zero ";
• Read each number, convert it to the corresponding upper-case Chinese character, and add the weight "marker, marker, and pickup". According to the number of arrays read, add "million" and "million" Yuan later ";
• The decimal part is processed as a one-dimensional array. Only two decimal places are retained, corresponding to the "angle" and "points". The number 0 is not processed;

 

The test number is 120,300, 7600.89.
