What library should I use in OSX for arbitrary precision arithmetic?

Question

I already tried GMP, MPFR. But I can not execute a simple section as shown below. BTW I have an LLVM compiler in Xcode. I am trying to compile, run it in IOS Simulator.

mpf_t a;

mpf_init2 (a, 256);

mpf_set_d (a, 0.7);

mpf_t b; mpf_init2 (b, 256);

mpf_set_d (b, 1.0);

mpf_t l; mpf_init2 (l, 256);

gmp_printf ("%. * Ff \ n", 5, a); --- 0.70000

gmp_printf ("%. * Ff \ n", 5, b); --- 1.00000

mpf_div (l, a, b);

gmp_printf ("%. * Ff", 5, l); --- 0.52502

Answer 1

Have you tried MPIR ? OpenSSL also provides a large library of numbers ...
