Pips  are points, or nominal currency change. A variety of instruments, or so-called currency pairs, are quoted with diverse accuracy,
 or different number of characters in their quotations. Most of the currencies are quoted with the accuracy of 0.0001, but some of them,
 for example YEN has cross-rates with the accuracy of 0.01. Usually Quotations are given in contracted form because big figures of quotations change gradually.
