Double-Precision Data

Double-precision data is defined only for the workstation. The iSeries, eServer™ i5, or System i5® does not support this data type. BASIC applications use double-precision data. This data type is a positive or negative number from 2.938735877055719 x 10^-39 to 1.701411834604692 x 10³⁸. Double-precision numbers are stored in 8 bytes, with 7 bytes representing the mantissa and 1 byte representing the exponent.
