Beyond the simple string or numeric classifications, Variant can make added distinctions regarding the specific nature of numeric information. For instance, you can have numeric information which represents a date or a time. While used with other date or time data, the result is expressed as a time or date. You can also contain a rich variety of numeric information ranging from Boolean values to enormous floating-point numbers. These distinct categories of information which can be contained in a Variant are called subtypes. Mostly time, you can just put the type of data you desire in a Variant, & the Variant acts in a way that is most suitable for the data it contains.
The following table illustrates the subtypes of data that a Variant can contain.

You can employ conversion functions to changed data from one subtype to another. Additionally, the VarType function returns information regarding how your data is stored within a Variant.
