This depends on the settings of the trading software. If the number format you entered does not meet the transaction requirements, the software does not allow you to enter it. Some software allows you to enter, but it will be handled according to certain principles. For example, if you enter a decimal point in the price of a certain variety, you will trade according to the standard of entering single digits when you buy more software, and trade according to the standard of dropping single digits when you buy it empty.
