What C   Library Handles Large Numbers Like Java's BigInteger?

Finding a C Library for Handling Large Numbers

In a project demanding the manipulation of exceptionally large numbers (up to 100 digits), you seek a C equivalent to Java's BigInteger class. Let's explore whether C offers such a standard or non-standard solution.

GNU Multiple Precision Arithmetic Library

For your purpose, the GNU Multiple Precision Arithmetic Library (GMP) emerges as a suitable candidate. Originally written in C, GMP provides a C class interface that enables convenient handling of large integers.

The mpz_class class in GMP offers a simple way to work with big integers. Here's an example:

int main() {
  mpz_class a, b, c;

  a = 1234;
  b = "-5678";
  c = a + b;
  cout << "Sum is " << c << "\n";
  cout << "Absolute value is " << abs(c) << "\n";

  return 0;
}

GMP simplifies operations on large numbers, allowing you to handle them with ease and efficiency.
