BigInteger constructor

BigInteger(
  1. String value, [
  2. int radix = 10
])

Creates a BigInteger from a string representation.

value the string representation radix the radix to use for parsing (default is 10)

A wrapper class for arbitrary precision integers.

This class wraps Dart's BigInt and provides Java-like functionality similar to Java's BigInteger class.

Example usage:

BigInteger a = BigInteger("123456789012345678901234567890");
BigInteger b = BigInteger.fromInt(42);
BigInteger sum = a + b;

print(sum.toString()); // Very large number
print(a.isProbablePrime()); // Primality test

Implementation

factory BigInteger(String value, [int radix = 10]) {
  return BigInteger._(BigInt.parse(value, radix: radix));
}
