Data Types in VB.Net
Visual Basic has several different data types available for storing different sorts of data values. It is important that data is stored in the correct type of variable.
Main data types
Data can be divided into two main groupings:
- Numeric data - which can be used to perform calculations
- Non-numeric data - such as names, addresses, etc
In general, the distinction is simple - if the data value is a number then it is numeric data. But this does not always work, there are times when it is better to store some numbers as non-numeric values.
If in doubt - ask yourself: Will I want to perform calculations on this value?
- If Yes - then use a numeric variable.
- If No - then use a non-numeric variable.
What sort of data is a telephone number? e.g. 01902 321234 The number is made up of digits, but would you ever want (for example) to double it?
