✐ Examples

1 Convert BigInt to Double

In this example,

  1. We create a BigInt object, num, initialized with a large integer.
  2. We use the toDouble method to convert the BigInt to a double.
  3. We print the result to standard output.

Dart Program

void main() {
  BigInt num = BigInt.parse('1234567895269666362');
  double result = num.toDouble();
  print('BigInt to double: $result');
}

Output

BigInt to double: 1234567895269666300

2 Convert Another BigInt to Double

In this example,

  1. We create a BigInt object, num, initialized with another large integer.
  2. We use the toDouble method to convert the BigInt to a double.
  3. We print the result to standard output.

Dart Program

void main() {
  BigInt num = BigInt.from(987654321);
  double result = num.toDouble();
  print('BigInt to double: $result');
}

Output

BigInt to double: 987654321

3 Convert Big Integer to Double

In this example,

  1. We create a BigInt object, num, initialized with a big integer.
  2. We use the toDouble method to convert the BigInt to a double.
  3. We print the result to standard output.

void main() {
  BigInt num = BigInt.from(1000000000);
  double result = num.toDouble();
  print('BigInt to double: $result');
