Size of Values Displayed

Although internal calculations are carried out using double precision numbers, results are only stored as single precision numbers (in order to reduce storage requirements). As a result, result values can only be relied upon to a maximum of 7 significant figures. For date outputs (e.g., outputs of the Milestone element An event element that records the time that an event occurs.), dates displayed in and around 2000 are only accurate to approximately 2 minutes.

This also means that when results are viewed in tables or charts, the range of values that can be displayed is between -1.2E-38 and 3.4E38.
