Program Plan Intro

Commonly used number types in java:

In java, there is a value which either references to the object or its primitive type. There are six primitive types in which four of them are integers and two for floating point numbers.

The following are the commonly used number types in java,

“int” type:

• An integer type represents the integer range values from smallest to largest values.
• The size of the “int” type can store “4 bytes” and the maximum range of integer can hold up to“2,147,483,648” and minimum range of “-2,147,483,648”.

“double” type:

• The “double” type is used to represent the double precision floating point values.
• The size of the “double” type can store up to “8 bytes” and the maximum range of double value can hold about $\pm {10}^{308}$ and it can store maximum of up to 15 significant decimal digits.
