JKBigInteger is a small library to facilitate easy working with big integers in Objective-C. JKBigInteger is a Objective-C wrapper around LibTomMath C library. It is inspired by the Java's BigInteger.
JKBigInteger *int1 = [[JKBigInteger alloc] initWithString:@"123"];
NSLog(@"%@ + %@ = %@", int1, int1, [int1 add:int1]);
JKBigInteger *int2 = [[JKBigInteger alloc] initWithString:@"10000001234567890123"];
JKBigInteger *int3 = [[JKBigInteger alloc] initWithString:@"123"];
NSLog(@"%@ - %@ = %@", int2, int3, [int2 subtract:int3]);
JKBigInteger *int4 = [[JKBigInteger alloc] initWithString:@"11111111111111111111"];
NSLog(@"%@ * %@ = %@", int4, int4, [int4 multiply:int4]);
JKBigInteger *int5 = [[JKBigInteger alloc] initWithString:@"10000001234567890123123123123"];
JKBigInteger *int6 = [[JKBigInteger alloc] initWithString:@"123"];
NSLog(@"%@ / %@ = %@", int5, int6, [int5 divide:int6]);JKBigInteger was created by Jānis Kiršteins
