Exact change的意思

"Exact change" is a term used to indicate that a transaction should be completed with the exact amount of money required, without the need for any change to be given. It is often used in situations where a person wants to pay for something with the exact amount of coins or bills, so that no additional currency needs to be provided in return.

For example, if the price of an item is $2.50, and you give the cashier $2.50 in exact change, you are using "exact change." This is in contrast to giving more money than necessary and receiving change back, or not having the exact amount and needing to be given the correct currency.

The term can be used in various contexts, such as when paying for something in person, using a vending machine, or any situation where money is exchanged for goods or services. It is particularly useful in situations where making change is inconvenient or where the recipient does not have the necessary change available.
