Peru is a free exchange rate country. Its local currency, the Peruvian new sol, is directly linked to the US dollar, and the US dollar can also circulate freely in the local area. All trading places have a clear exchange rate of the day, which is generally reserved to two decimal places. In addition, there are many local currency exchanges, CAJA, which can also buy and sell these two currencies freely, but with two decimal places, while banks trade according to four decimal places.
