What to know about OMR

OMR has three decimals, one more than most currencies. An MT amount such as field 32A may have up to three digits after the comma, for example 1250,750; a fourth is rejected with error code C03 (see how to read field 32A). Systems that keep every amount with two decimals round OMR amounts, and prices and quantities of OMR instruments sent over FIX need three decimal places of precision.
