Bigint In C

C library that supports very large numbers (upto 1000 digits), basic Arithmetic operations and a set of mathematical functions

Functions:

• CompareBigint : This function accepts two Bigints(char array) compares them and returns an integer.

int CompareBigint(const char* Bigint1, const char* Bigint2)

1. If Bigint1 > Bigint2 returns 1
2. If Bigint1 < Bigint2 returns -1
3. If Bigint1 = Bigint2 returns 0

• BigintAdder : This Function returns Addition of two Bigints(char array), supports non-negative integers.

char* BigintAdder(const char* Bigint1, const char* Bigint2)

• BigintDiffer : This Function returns Difference of two Bigints(char array), supports non-negative integers.

char* BigintDiffer(const char* Bigint1, const char* Bigint2)

• BigintMultiplier : This function performs Multiplication of two Bigints(char array) using standard multiplication algorithm.

char* BigintMultiplier(const char* Bigint1, const char* Bigint2)

• BigintFactorial : This function returns the Factorial of a given number passed as an argument.

char* BigintFactorial(unsigned integer num)

• BigintFibonacci : This functions returns the nth Fibonacci number passed as an argument.

char* BigintFibonacci(unsigned integer num)

test.c

• A test case file for checking correctness of all functions and arithmetic operations.

bigint.h

• Header file that contains all mathematical functions and arithmetic operations.

implement.h

• Contains implementation of all functions.
