So, for example, twelve thousand five hundred with a decimal of five zero is written differently depending on the country:
In the USA, Mexico, or the UK, it would be written: 12 500.50 or 12,500.50
In Spain, South Africa, or Brazil, it would be: 12 500,50 or 12.500,50
因此，例如，12500 个小数点为 5 个零的写法因国家/地区而异：
在美国、墨西哥或英国，它会写成：12 500.50 或 12,500.50
在西班牙、南非或巴西，它将是：12 500,50 或 12.500,50
