Java floating-point-to-renminbi reading method

Java floating-point-to-renminbi reading method

• The "integer part" of the number, starting from the single digit, 4 numbers are divided into a group, the highest bit no number on 0, and record the total number of arrays, a total of 3 groups, also 3*4 two-dimensional array;
• For each array of uniform processing, and finally the most beginning of the "0 minus", "Million", "million" "Yuan" before the word "0" removed;
• When reading to 0 o'clock, check if the previous one is 0, if the previous one is 0, then do not handle, if the previous one is not 0 or the previous one does not exist, all note "0";
• Read each number, converted to the corresponding uppercase Chinese characters, and add the weight "thousand, Bai, pick up", according to read the first few arrays, followed by the corresponding "million", "million" "Yuan";
• The "fractional part" to do one-dimensional array processing, only two decimal places, corresponding to the "angle" and "minute", the number 0 is not processed;

The test number "120, 3005, 7600.89", read: One Bai hundred billion three thousand Wu Wu Qian seven thousand yuan Ba angle nine points.
