Decimal computer Decimal computer Decimal computers are computers which can represent numbers and addresses in decimal as well as providing instructions to operate on those numbers and addresses directly in decimal, without conversion to a pure binary representation. Some also had a variable wordlength, which enabled operations on numbers with a large number of digits. Early computers that were exclusively decimal include the ENIAC, IBM NORC, IBM 650, IBM 1620, IBM 7070. In these machines, the basic unit of data was the decimal digit, encoded in one of several schemes, including binary-coded decimal or BCD, bi-quinary, excess-3, and two-out-of-five code. Except for
Percentage in point Percentage in point In finance, specifically in foreign exchange markets, a percentage in point or price interest point (pip) is a unit of change in an exchange rate of a currency pair. The major currencies (except the Japanese yen) are traditionally priced to four decimal places, and a pip is one unit of the fourth decimal point: for dollar currencies this is to 1/100th of a cent. For the yen, a pip is one unit of the second decimal point, because the yen is much closer in value to one hundredth of other major currencies. A pip is sometimes confused
