Big Integer in C

C-BigInteger

Big integer for C language

This code allows work with integers that don't fit in types defined in C. It represents numbers in binary two's complement with array of booleans.

Example

int lenNum1 = 3;
int lenNum2 = 2;
bool binaryNum1[] = {true, true, false}; // 6
bool binaryNum2[] = {true, false}; // 2
bool isNegative1 = false;
bool isNegative2 = true;

BigInteger *bigInteger1 = initBigInteger(isNegative1, binaryNumber1, lenNum1); // 6
BigInteger *bigInteger2 = initBigInteger(isNegative2, binaryNumber2, lenNum2); // -2

BigInteger *result = add(bigInteger1, bigInteger2); // 6 - 2 = 4 = 0 100(two's complement);
