Integer in Dart
Educative Answers TeamIn the Dart programming language, an integer is represented by the int keyword. As we may know, integers include whole numbers (i.e., non-decimal positive and negative numbers). For every integer, four bytes are allocated in the memory.
Code
import 'dart:convert';
void main() {
// Two integers
int num1 = 6;// positive number
int num2 = -6;// negative number
// printing both numbers
print(num1);
print(num2);
}The code below throws an error because it is not possible to assign a fractional value to an integer.
For fractional values, we use
doubledatatype.
import 'dart:convert';
void main() {
// Two integers
int num = 6.56;// fractional value
// printing both numbers
print(num);
