The sum of money given to a petty cashier out of which small payments are made is known as a "float". It is an amount of money that is provided by a company or organization to the petty cashier to facilitate small, routine transactions. The petty cashier uses the float to make purchases, pay for small expenses, or provide change to customers. At the end of the day, the petty cashier is required to account for the expenses incurred using the float, and any unused funds are returned to the company or organization. The float helps to simplify and speed up small transactions and reduce the need for the petty cashier to access the company's main cash account for small expenses.
