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.
