Abstract

The invention provides a currency exchange data processing method and device and a currency exchange system. The method comprises after receiving the data value and the currency information after currency exchange, the method obtaining the secondary currency digits corresponding to the currency information through the pre-established monetary secondary currency digits information table, and performing rounding operation on the data value according to the secondary currency digits to obtain the currency exchange data result corresponding to the secondary currency digits of the converted currency, so that not only the accuracy of currency exchange is improved, but also the data value can be rounded according to the precision corresponding to the number of secondary currency, and the data value can be rounded quickly only by setting up the information table of secondary currency number in advance and calling the function of rounding function.

Description

technical field [0001] The invention belongs to the technical field of currency exchange, and in particular relates to a currency exchange data processing method, device and currency exchange system. Background technique [0002] Currency conversion refers to the conversion of one currency into another currency, that is, the amount value of one currency needs to be calculated and converted into the amount value of another currency based on the current quotation or exchange rate. The existing method of realizing currency conversion is to obtain the exchange rate between the initial currency and the conversion currency according to the input amount value, the initial currency and the exchange currency, and convert the amount value into the converted amount value according to the exchange rate and output it. Complete the currency exchange. [0003] However, the digits of auxiliary currency of different currencies in the world are not the same, such as the US dollar and RMB wit...
