# Numeric Types in Scala

Numeric type contains integer and floating-point data. In Scala program, Float, Double, Int, Short, Long come under the number type. In this tutorial on numeric types in Scala, we will learn the initialization and functioning of all data types that come under numeric type.

## Scala Numeric Types

Numeric type in Scala deals with all types that are stored in numerical. The data type that is used is decimals (float and Double) and integers (Int, Short, Long).

### 1) Int Data Type in Scala

The int data type stores integer variables that take memory location of 4 bytes. The value of int data type ranges from -2147483648 to 2147483647.

Syntax of initialize Integers:

```    var a = 343 // Without date type
var a : Int = 4623 // With data type
```

Example code for Int data type

```object MyClass {
def main(args: Array[String]) {
var ch = 324
var b : Int = 3342
println("The value of int ch is " + ch)
println("Value of integer b is " + b)
}
}
```

Output

```The value of int ch is 324
Value of integer b is 3342
```

### 2) Short Data Type in Scala

The short data type stores the integer value of variables that takes memory location of 2 bytes. The value of short data type ranges from -32768 to 32767.

Syntax of initialize short Integers

```    var a = 343 // Without data type will give int
var a : Short = 4623 //without this variable will be integer.
```

Example code for short data type

```object MyClass {
def main(args: Array[String]) {
var b : Short = 3342;
println("Value of short integer b is " + b);
}
}
```

Output

```Value of short integer b is 3342
```

### 3) Long Data Type in Scala

The long data type stores integer value to variables that takes memory location of 8 bytes. The value of long data type ranges from -9223372036854775808 to 9223372036854775807.

Syntax of initialize long Integers

```    var a = 343 // Without date type will give int
var a : Long = 4623 //without this variable will be integer.
```

Example code for short data type

```object MyClass {
def main(args: Array[String]) {
var b : Long = 33423452;
println("Value of long integer b is " + b);
}
}
```

Output

```Value of long integer b is 33423452
```

### 4) Float Data Type in Scala

The float data type stores decimal values to its variables that takes memory location of 4 bytes. The value of float data type ranges from -3.4E+38 to +3.4E+38 i.e. single precision.

Syntax of initialize Float values

```    var variable_name = 343.43
var variable_name : Float = 463.876
```

Example code for float data type

```object MyClass {
def main(args: Array[String]) {
var b : Float = 33.97f;
println("Value of Float value b is " + b);
}
}
```

Output

```Value of Float value b is 33.97
```

### 5) Double Data Type in Scala

The double data type stores decimal values to its variables that takes memory location of 8 bytes. The value of float data type ranges from IEEE 754 double-precision float.

Syntax of initialize Float values

```    var variable_name = 3463.434565 // this will be initialized as float
var variable_name : Double = 46763.87634
```

Example code for double data type

```object MyClass {
def main(args: Array[String]) {
var b : Double = 345453.978765;
println("Value of Double value b is " + b);
}
}
```

Output

```Value of Double value b is 345453.978765
```
