Case Amount Conversion
In actual work, when we fill in RMB data, such as reimbursement of travel expenses and IOUs, we need to write the amount in uppercase. Sometimes we need to convert the lowercase amount in a series of forms to uppercase. This is the conversion of uppercase and lowercase amounts. For example, The capitalized amount of 10 802.54 is: ten thousand and five thousand dollars and four cents.
[Analysis]
The method to convert lowercase amounts to uppercase amounts is as follows.
(1) Find the number of integers and decimals corresponding to the lowercase amount.
(2) Convert the integer part and the decimal part to uppercase amounts respectively, that is, convert the Arabic numeral "0123456789" to "Zero One Two Three Four Wu Lu Qi Lu Jiu", and add the currency unit "Fen Jiao Yuan Shi" Hundred Thousand Thousand Thousand Thousand Billion Thousand Thousand Thousand Thousand Thousand Thousand Millions".
When converting the integer part to uppercase amount, if a certain digit of the integer part is 0, it needs to be dealt with in the following situations: ①The first digit is 0, if the second digit is not: or there are other characters behind , The input is wrong: otherwise, the output "zero yuan". ② If the number of 0 is not the first digit, and is not a hundred million, ten thousand yuan, or yuan, it needs to output "zero"; if it is a hundred million, ten thousand yuan, or yuan, it needs to increase the RMB unit.
In other cases, directly convert Arabic numerals to uppercase amounts and output currency units.
When converting the decimal part, when a certain digit is 0, if the digit is the first digit after the decimal point, then output "zero": if the first and second digits of the decimal point are both 0, output "integer". In other cases, the Arabic numerals are directly converted into uppercase amounts and the currency units are output.
