In the Dart programming language, **`double`** is a data type that stores decimal numbers (fractional numbers). For each `double` variable, eight bytes are allocated in the memory.

> If you try to assign any integer value to the `double` variable then, by default, it will be cast to the `double` data type. For example, $6$ would be represented as $6.0$.

import 'dart:convert';
void main() {
    //Fractional value
    double num1 = 6.532;
    // Integer Value
    double num2 = 6;// cast this integer to double
    // printing both numbers
    print(num1);
    print(num2);
}
