**Extended precision** refers to floating point number formats that provide greater precision and more exponent range than the basic floating point formats. In contrast to *extended precision*, arbitrary-precision arithmetic refers to implementations of much larger numeric types (with a storage count that usually is not a power of two) using special software (or, rarely, hardware).

### Famous quotes containing the words precision and/or extended:

“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical *precision* that twice two is seven.”

—Anton Pavlovich Chekhov (1860–1904)

“The civility which money will purchase, is rarely *extended* to those who have none.”

—Charles Dickens (1812–1870)
