✐ Examples

1 Flooring a decimal number

In this example,

  1. We create a num variable number1 with the value 5.6 and another variable number2 with the value -3.2.
  2. We use the floorToDouble() method to get their floor values as double.
  3. We then print the results to standard output.

Dart Program

void main() {
  num number1 = 5.6;
  num number2 = -3.2;
  double result1 = number1.floorToDouble();
  double result2 = number2.floorToDouble();
  print('Floor of $number1: $result1');
  print('Floor of $number2: $result2');
}

Output

Floor of 5.6: 5
Floor of -3.2: -4

2 Flooring an integer

In this example,

  1. We create a num variable number with the value 10.
  2. We use the floorToDouble() method to get its floor value as double.
  3. We then print the result to standard output.

Dart Program

void main() {
  num number = 10.0;
  double result = number.floorToDouble();
  print('Floor of $number: $result');
}

Output

Floor of 10: 10
