Dollars to Pounds

In fact, has rarely been possible to exchange currency at a fine listed on the stock market. And market makers who match buyers and sellers take a commission. This is achieved by trying to publish quote / offer. For example, if you bid to buy the British Pounds to do on the purchase price of say, 115 Pounds to the dollar, and if you offer to sell the yen may do so at 125 pounds per dollar.

There is an example of some precious calculator where you can convert any kind of currency to any currency like "dollars to pounds"
