In programming, data types play a crucial role in defining the nature of variables and values that can be stored in them. One such category of data types is integral data types, which are used to represent whole numbers without any fractional or decimal parts. These data types are essential for performing mathematical calculations and representing quantities in various programming languages.

## What are Integral Data Types?

Integral data types, also known as integer data types, are used to store whole numbers. They do not include any fractional or decimal parts, making them suitable for representing quantities that require precision without any loss of information. These data types come in different sizes and ranges based on the programming language.

### Common Integral Data Types

Let’s take a look at some common integral data types:

**int:**This is a standard integral type that stores signed integers. Its size and range depend on the programming language but typically include values from -2^{31}to 2^{31}-1.**short:**This type is used to store smaller signed integers compared to int.Its size is usually half of an int, allowing it to represent values ranging from -2

^{15}to 2^{15}-1.**long:**A long integer type is used when you need an extended range of values compared to int. It typically has a size twice that of an int, accommodating values from -2^{63}+1 to 2^{63}-1.**byte:**This is the smallest integral type available, storing small signed integers ranging from -128 to 127. It is often used when memory optimization is a concern.

## Which Is Not an Integral Data Type?

Now that we know what integral data types are, let’s discuss which data type does not belong to this category. The answer is __floating-point__ data types.

Floating-point data types, also known as real or decimal data types, are used to represent numbers with fractional or decimal parts. They include values like 3.14 or -0.5, which cannot be represented by integral data types precisely.

Examples of floating-point data types include:

**float:**This type represents single-precision floating-point numbers and typically occupies 4 bytes of memory.**double:**A double-precision floating-point number takes twice the memory of a float and provides higher precision for calculations.

__Note:__ It’s important to understand the distinction between integral and floating-point data types because they have different use cases and limitations in programming.

## In Conclusion

In summary, integral data types are used to store whole numbers without any fractional or decimal parts. They are essential for performing mathematical calculations accurately and representing quantities precisely in programming languages. Examples of integral data types include int, short, long, and byte.

On the other hand, floating-point data types are used for representing numbers with fractional or decimal parts. They provide higher precision but have different use cases compared to integral data types. By understanding these distinctions, you can choose the appropriate data type for your programming needs and ensure accurate representation of numerical values.
