JKBigInteger
About JKBigInteger
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.
Example
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]);
unsigned int numBytesInt5 = [int5 countBytes];
unsigned char bytes[numBytesInt5];
[int5 toByteArrayUnsigned:bytes];
for(unsigned i = 0; i < numBytesInt5; i++)
{
NSLog(@"Byte %d: %X", i, bytes[i]);
}
JKBigDecimal *dec1 = [[JKBigDecimal alloc] initWithString:@"2015.987"];
JKBigDecimal *dec2 = [[JKBigDecimal alloc] initWithString:@"5.4"];
NSLog(@"%@ + %@ = %@", dec1, dec2, [dec1 add:dec2]);
NSLog(@"%@ - %@ = %@", dec1, dec2, [dec1 subtract:dec2]);
NSLog(@"%@ * %@ = %@", dec1, dec2, [dec1 multiply:dec2]);
NSLog(@"%@ / %@ = %@", dec1, dec2, [dec1 divide:dec2]);
NSLog(@"%@ %% %@ = %@", dec1, dec2, [dec1 remainder:dec2]);
JKBigDecimal *dec3 = [[JKBigDecimal alloc] initWithString:@"0.99"];
NSLog(@"%@ pow 365 = %@", dec3, [dec3 pow:365]);Installation
You can easily add JKBigInteger to your project with CocoaPods by adding it to your Podfile:
pod 'JKBigInteger', '~> 0.0.1'
