Question

What is the difference between numeric and nonnumeric data types?

Answer 1

Numeric Data Types

     

Numeric data types are types of data that consist of numbers, which can be computed mathematically with various standard operators such as add, minus, multiply, divide and so on. Examples of numeric data types are your examination marks, your height, your weight, the number of students in a class, share values, price of goods, monthly bills, fees and etc. In Visual Basic, numeric data are divided into 7 types, depending on the range of values they can store.

Calculations that only involve round figures or data that don't need precision can use Integer or Long integer in the computation. Programs that require high precision calculation need to use Single and Double decision data types, they are also called floating point numbers. For currency calculation , you can use the currency data types. Lastly, if even more precision is requires to perform calculations that involve a many decimal points, we can use the decimal data types.

Non-numeric Data Types

Nonnumeric data types are data that cannot be manipulated mathematically using standard arithmetic operators. The non-numeric data comprises  text or string data types, the Date data types, the Boolean data types that store only two values (true or false), Object data type and Variant data type .

Answer 2

Numeric VS non-numeric data types:

Numeric data type:

• Numeric data types are numbers kept in database columns.

• Numerical data is data that is quantifiable, such as time, height, weight, amount, and so on.  

Non numeric data type:

• A non- numeric data bring up to a categorical data.

• Numeric data types are numbers kept in database columns. These data types are classically grouped by: Exact numeric types, values where the exactness and scale need to be preserved.
