Numerical Data Types Summary

In the preceding chapters, we covered the numerical data types int, float, and double.
Additionally, we discussed type modifiers such as short, long, and unsigned.
By combining these types and modifiers, we can select the most appropriate data type for our specific task.

However, it's important to note that in C++, the unsigned and short type modifiers cannot be used with floating-point types such as float and double.

With that being said, here is a table containing all the types:

Data Type	Size (bytes)	Range	Precision
`short`	2	-32,768 to 32,767
`unsigned short`	2	0 to 65,535
`int`	4	-2,147,483,648 to 2,147,483,647
`unsigned int`	4	0 to 4,294,967,295
`long`**	8	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
`unsigned long`**	8	0 to 18,446,744,073,709,551,615
`float`	4	±1.2e-38 to ±3.4e+38	7 digits
`double`	8	±2.2e-308 to ±1.8e+308	15 digits
`long double`	8 to 16*	Huge*	15-33 digits*

* means it depends on a system
** on Windows, long long instead of long
