We divide the amount that needs to be expressed into two usage scenarios 1. Marketing 2. Finance

Marketing includes shopping mall purchases, operating banners, discounts and promotions, etc.

< p> Financial categories include payment, lending, financial management, etc.

Unless the amount has decimal places, it is not recommended to use decimal places in marketing scenarios, because marketing itself is a process of quickly converting traffic. In this process The value of the product/offer needs to be presented to the user in the clearest and fastest way. If the amount is an integer but .00 is added, this will undoubtedly increase the user's reading cost. Of course, if the product itself has decimal places, it will be displayed to the decimal places. In most user purchase scenarios, the amount after the decimal place is often not considered too much. Therefore, when designing the UI, the font of the decimal place of the amount can be appropriately adjusted to enhance the readability of the amount.

Financial scenarios involve payment, transfer and other money transactions, so they need to be rigorous and safe. Users will also pay more attention to the specific value of the payment amount. At this time, displaying .00 will appear rigorous and standardized. .

Take Taobao transactions as an example. When browsing products, the prices displayed on the marketing banner are generally integers, and occasionally fields such as "9.9 Free Shipping" are not broken down into digits. When you click on the product to browse the details page, the product price will not display .00. But when the user selects the quantity and type of goods, the price will change to .00. This is especially true for the numbers displayed in the order details when submitting the order. Click Pay to select the payment method, and the price paid at this time will also display .00.

"?" not only serves as the writing symbol of RMB, but also represents the currency system of RMB and the unit "yuan" of RMB. It is also the symbol of Japanese currency. The emergence of the "?" symbol can be traced back to the Republic of China.

When we write the amount of RMB, we are accustomed to writing "RMB symbol"? or "￥" before the Arabic numerals. This is the abbreviation symbol for RMB in our country.

"￥" "" is not only the written symbol of RMB, but also represents the currency system of RMB and the unit "yuan" of RMB. When filling in amounts with Arabic numerals in economic transactions and accounting, adding a "?" before the first digit of the amount can prevent Adding a number before the amount can also indicate the amount in RMB. Since ? itself represents the unit of RMB, there is no need to add the word "yuan" after the amount if "?" is added before the amount. /p>

The difference between the two when used in products is that "?" is more graphical and is usually placed in front of a number, so it can quickly convey the meaning of an amount to the user, while yuan is generally text. Putting it after the number is not very expressive of the amount. Users are already familiar with the meaning of "?"

If it involves scenarios such as foreign exchange conversion, the ? symbol is similar to the symbols of other currencies. It is not suitable and can be expressed in RMB CNY.

The thousand separator is actually the comma in the number. According to Western customs, people add a symbol to the number to avoid the number of digits being too large. It is difficult to see its value, so people add a comma thousands separator to every three digits in the number to make it easier to recognize the value.

Thousands are widely used in foreign products, which is related to English language habits. There are only units such as thousand (thousand), million (million), billion (billion) in English, so using thousandths is more consistent with English reading. Because Chinese has more unit expressions, when designing products for domestic users, you need to be careful about using thousandths and consider using Chinese units more.
