Decimal pricing refers to the quoting of security prices in decimal instead of fractions. Historically, stocks or other equities are priced in fractions such as 44 1/4 a share which is $44.25 a share in decimals. Decimal pricing also allows for more accurate publishing of prices. The Securities and Exchange Commission in the United States pushed regulations for decimal pricing which started in 1997, it was completed and spread throughout the rest of the global equities markets by 2001. U.S treasuries however still trade in whole numbers and 32nds.
