What are the Data Types in VB Script and Explain About Variant?

Data Types:
VB Script has only one data type called a Variant. A Variant is a special kind of data type that can contain different kinds of information, depending on how it is used and It represents everything Int. String, Float, Date, Boolean and  Null etc. Because Variant is the only data type in VBScript, it's also the data type returned by all functions in VB Script.

At its simplest, a Variant can contain either numeric or string information. A Variant behaves as a number when you use it in a numeric context and as a string when you use it in a string context. That is, if you're working with data that looks like numbers, VBScript assumes that it is numbers and does the thing that is most appropriate for numbers. Similarly, if you're working with data that can only be string data, VBScript treats it as string data.

Variant Sub Data Types
Beyond the simple numeric or string classifications, a Variant can make further distinctions about the specific nature of numeric information. For example, you can have numeric information that represents a date or a time. When used with other date or time data, the result is always expressed as a date or a time. Of course, you can also have a rich variety of numeric information ranging in size from Boolean values to huge floating-point numbers. These different categories of information that can be contained in a Variant are called subtypes. Most of the time, you can just put the kind of data you want in a Variant, and the Variant behaves in a way that is most appropriate for the data it contains.
