Casting and Variable Range

Casting: Turning on data type into another
Syntax:
Just put the desired type in parentheses in front of the value
Ex.
Double x = 10.3;
Int y = (int)x;
The y becomes 10, otherwise, you would get an error
You can also just make one number a double, by just adding a .0 to the number

Implicit casting: Java changes type automatically
Ex.
Java will turn integers into doubles automatically

Integer Storage Limitations:

• An integer is stored in 32 bit, which means that there are “only”  2^32 ~ 4 billion combinations, so that is why the integer range is from -2,147,483,648 to 2,147,483,647
• Also written as Integer.MIN_VALUE AND Integer.MAX_VALUE

Casting a double to an int:
It truncates to the lowest whole number, it won’t round normally.
