## Int data type

In Dart, int is a built-in data type under Number category.

If Dart application is made for native platforms like Windows, Linux, Mac, etc., variables of type int can hold values in the range [-263, 263-1].

If Dart application is made for web, then variables of type int in JavaScript can hold values in the range [-253, 253-1].

## Define Int Variable

Use `int` keyword to define a variable of type integer, as shown in the following.

`int x = 25;`

In Dart, we can assign an integer value to a variable declared using `var` keyword, then the type of the variable would become int.

`var x = 25;         // type of x is int`

## Operations on Integer Values

We can perform arithmetic operations like addition, subtraction, multiplication, division, etc., on values of integer type.

main.dart

```void main() {
int x = 5;
int y = 4;
print('x + y = \${x + y}');
print('x - y = \${x - y}');
}```

Output

```x + y = 9
x - y = 1```
