美元数字大写转换器

当然，我可以帮助您将美元数字转换为大写。以下是一个简单的示例，说明如何将数字转换为美元的大写形式：

```python

def number_to_english(num):

under_20 = ['Zero', 'One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten',

'Eleven', 'Twelve', 'Thirteen', 'Fourteen', 'Fifteen', 'Sixteen', 'Seventeen', 'Eighteen', 'Nineteen']

tens = ['', '', 'Twenty', 'Thirty', 'Forty', 'Fifty', 'Sixty', 'Seventy', 'Eighty', 'Ninety']

if num < 20:

return under_20[num]

elif num < 100:

return tens[num // 10] + ('' if num % 10 == 0 else ' ' + under_20[num % 10])

else:

return under_20[num // 100] + ' Hundred' + ('' if num % 100 == 0 else ' ' + number_to_english(num % 100))

def currency_to_english(amount):

if amount < 0:

return 'Negative ' + currency_to_english(-amount)

dollar_part = amount // 100

cent_part = amount % 100

dollar_english = number_to_english(dollar_part) + ' Dollars'

cent_english = number_to_english(cent_part) + ' Cents' if cent_part > 0 else ''

return dollar_english + (' and ' + cent_english if cent_english else '')

Example usage:

amount = 12345.67

print(currency_to_english(amount))

```

这段代码定义了两个函数：`number_to_english`用于将数字转换为英语单词，`currency_to_english`用于将货币金额转换为英语大写形式。例如，输入`12345.67`将会输出`Twelve Thousand Three Hundred Forty-Five and Sixty-Seven Cents`。
