In a default Galaxy, which of the following objects will you find?

In a default Galaxy within the AVEVA Application Server, one of the primary object types you will find is the $Double object. This type is used to represent double-precision floating-point numbers, allowing for high-precision calculations that are essential in various applications, especially those involving engineering and scientific calculations.

Double-precision is particularly useful in scenarios where accuracy is vital, such as when processed data needs to maintain a high degree of precision over a range of values. In comparison to other numerical types, the $Double type can store much larger and more accurate values than integers or single-precision floating points (like $Float), making it advantageous for applications that require detailed numerical representation.

This versatility makes the $Double object a fundamental component in the Galaxy, supporting various functionalities and data manipulations needed for application development within the AVEVA framework. Understanding and utilizing this object is crucial for building effective applications that require numerical data handling.
