Dart BigInt toRadixString()
Syntax & Examples

BigInt.toRadixString() method

The `toRadixString` method of BigInt class in Dart converts a BigInt to a string representation in a specified radix.

Syntax of BigInt.toRadixString()

The syntax of BigInt.toRadixString() method is:

 String toRadixString(int radix)

This toRadixString() method of BigInt converts this to a string representation in the given radix.

Parameters

ParameterOptional/RequiredDescription
radixrequiredthe radix (base) for the string representation

Return Type

BigInt.toRadixString() returns value of type String.


✐ Examples

1 Convert to Binary

In this example,

  1. We create a BigInt object, num, initialized with 255.
  2. We use the toRadixString method with a radix of 2 to convert the BigInt to binary representation.
  3. We print the binary representation to standard output.

Dart Program

void main() {
  BigInt num = BigInt.from(255);
  String binary = num.toRadixString(2);
  print('Binary representation: $binary');
}

Output

Binary representation: 11111111

2 Convert to Hexadecimal

In this example,

  1. We create a BigInt object, num, initialized with 12345.
  2. We use the toRadixString method with a radix of 16 to convert the BigInt to hexadecimal representation.
  3. We print the hexadecimal representation to standard output.

Dart Program

void main() {
  BigInt num = BigInt.from(12345);
  String hexadecimal = num.toRadixString(16);
  print('Hexadecimal representation: $hexadecimal');
}

Output

Hexadecimal representation: 3039

3 Convert to Octal

In this example,

  1. We create a BigInt object, num, initialized with 98765.
  2. We use the toRadixString method with a radix of 8 to convert the BigInt to octal representation.
  3. We print the octal representation to standard output.

Dart Program

void main() {
  BigInt num = BigInt.from(98765);
  String octal = num.toRadixString(8);
  print('Octal representation: $octal');
}

Output

Octal representation: 300715
