✐ Examples

1 Floor to double of an integer

In this example,

  1. We create an integer variable num with the value 4.
  2. We use the floorToDouble() method to convert it to a double.
  3. We then print the result to standard output.

Dart Program

void main() {
  int num = 4;
  double floorDouble = num.floorToDouble();
  print('Floor to double of $num: $floorDouble');
}

Output

Floor to double of 4: 4

2 Floor to double of a negative integer

In this example,

  1. We create an integer variable negativeNum with the value -3.
  2. We use the floorToDouble() method to convert it to a double.
  3. We then print the result to standard output.

Dart Program

void main() {
  int negativeNum = -3;
  double floorDoubleNegative = negativeNum.floorToDouble();
  print('Floor to double of $negativeNum: $floorDoubleNegative');
}

Output

Floor to double of -3: -3

3 Floor to double of an integer

In this example,

  1. We create an integer variable integerNum with the value 7.
  2. We use the floorToDouble() method to convert it to a double.
  3. We then print the result to standard output.

Dart Program

void main() {
  int integerNum = 7;
  double floorDoubleInteger = integerNum.floorToDouble();
  print('Floor to double of $integerNum: $floorDoubleInteger');
}

Output
