Extended Precision

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).
