您可以尝试免费使用" LibTomMath "(作者放弃了该项目，将其作为公共领域).它开箱即用，无需任何配置，只需将所有bn _ *.c和tommath * .h放入您的Xcode项目中，即可开始使用.

You can try "LibTomMath" which is opensource and free (the author give away this project as public domain). It works out of the box without any configuration, just put all bn_*.c and tommath*.h to your Xcode project and you are ready to go.

#import "tommath.h"

mp_int number1, number2, number3;

mp_init(&number1);
mp_init(&number2);
mp_init(&number3);

mp_read_radix(&number1, "0a120edfff558c98a73015d5d67e8990", 16);
mp_read_radix(&number2, "12e6f45d698c7b7009a841c1348d6ff4", 16);

mp_mul(&number1, &number2, &number3);

char output[1000];
mp_toradix(&number3, output, 16);
NSLog(@"number3:%s", output);

mp_div(&number3, &number1, &number2, NULL);
mp_toradix(&number2, output, 16);
NSLog(@"number2:%s", output);
