## Description

Draco implements two basic data types: variables and constants. Constants refer to scalar values that are defined independent from any series data. In other words, a Draco constant value does not vary within panel data or time series. All constant values are stored in double precision floating point format.
A constant value, however, can be changed at any time. Constants may be accessed from the Constants Window at any time. Constants can be created, modified and deleted.
Constants can also be used similar to standard Variables within dialogs where equations may be entered.
