Numeric Data Types
In numerical datatypes, there are two basic data types as shown below:
1. Integer Data Type
2. Floating points Data Type(float and double)

You can use `int` when you need to store integers and whole number without decimals (e.g., 95 or 1000) and `float` or `double` when use you need a decimal number (e.g., 5.87 or 7.9715).
• Integer Data Type
You can use `int` is use to store integers and whole numbers without decimals (e.g., 95 or 1000).
The int keyword is used to indicate integers.

Example of int:
Output : 140
• Floating points Data Type
`float` or `double` are to store floating-point numbers (e.g., 5.87 or 7.9715) and exponentials( e.g., 10E13)

The size of float is 4 bytes and the size of double is 8 bytes. Hence, double has two times the precision of float. To learn more, visit C++ float and double.
Example of float:
Output : 98.76

Example of double:
Output : 65.7699
As mentioned above, these two data types are also used for exponentials. For example,
